POLICY ON SUMMATIVE ASSESSMENT
All feedback on coursework used in assessment, including mid-year class
exam/class test marks and laboratory grades, is strictly provisional for
your guidance only, and is subject to ratification by the Board of Examiners
and external examiners at the end of the academic year. You must retain
all copies of assessed work (lab notebooks, exam scripts, etc.) and have
them available for inspection by the examiners if requested at the end
of the year. You will be given reasonable advance warning should this be
required.
PLAGIARISM
Degrees from Glasgow University recognise personal achievement. Plagiarism
or copying is academic fraud and a serious offence against University discipline.
Plagiarism is the submission of someone else's work as one's own without
acknowledgment. If you use someone else's work - words, ideas, data - you
should say so. Direct quotations should be placed in quotation marks.
This regulation applies to all work submitted for assessment, including
lab reports, class tests and research projects unless you have specifically
been told otherwise, for example in the case of a group project or when
a number of students share experimental data.

STUDENT PROGRESS
Your performance of class work will be considered satisfactory only if
:
(a) you regularly attend lectures and tutorials,
(b) you carry out a research project which - in the Chemistry Department
- should follow the timetable given later in this handbook and, in this
case,
(c) you give a short oral presentation in week 19, and
(d) you provide the Chemistry Department with one copy of a thesis
on your project by the first day of the third term.
EXAMINATIONS
The chemistry component of the M.Sci. final degree examination consists
of a research project and three written papers. The thesis project will
be assessed on the basis of the thesis itself, the work performed in the
laboratory and an oral examination on the thesis work.
The project contributes a maximum of 9% to the final mark, with the other
contributions:mathematical and computational methods for physics (5%),
course work in each of chemistry and physics (36.5%) and -3M laboratory
work in each subject (6.5%). The chemistry-3M written mark contributes
up to 20% of the course work mark.
All students must be available for oral examination by the external examiners
on Tuesday, 16th June, 1998. This is an integral part of the degree examination.
CAREERS TALK AND DISCUSSION
Tuesday 4th November 1 pm Organic Lecture Theatre.
Dr. N. Winterton, ICI, "To do or not to do a PhD", followed by
open ended discussion.
Professor Winfield and Dr. Dymond will arrange individual interviews for
all students early in Term 1 to discuss their choices of a future career.
LECTURES
Alchemist Club and local R.S.C. meetings: Attendance at these talks, which
are held on Thursdays at 4 pm, and at the Irvine Review Lectures is recommended
and encouraged. The Irvine Review Lectures will be given in St. Andrews
during April, 1998.
FOURTH YEAR PROJECT TIMETABLE
Dr Peacock (RDP) is in overall charge of fourth year projects.
Week 1 Project supervisors announced to class.
Students contact supervisors and agree on projects.
Week 2 Supervisors give students two copies of a synopsis of the
project including a title and leading references.
One copy of the project synopsis should be given to RDP.
Week 4 Project assessors announced.
Students contact assessors.
Week 5 Practical work may begin from the start of this week provided
a COSHH form has been completed, signed by the supervisor and given to
Mrs M Nutley (Room B4-20a). If the nature of the research changes during
the project new COSHH forms must be completed.
Week 10 Students give their thesis introduction to RDP who will
pass it on, with any comments, to the supervisor. The supervisor will return
the introduction in the first week of term 2.
The Introduction should be around 5 -10 pages, word processed,
and include a full list of references.
Week 15 Friday: Last day of practical work.
Week 19 Thesis talks (15 mins - not assessed).
Week 20 Friday: Final draft of thesis approved by supervisor.
Week 21 Monday: Last day for submission of theses. One copy to
be supplied to Mr R Munro - he will make a copy (or copies) for the Department,
and bind and return the original.
Weeks 22-23 Oral examinations. These will be conducted by the
assessor and a second member of staff. The supervisor will not be present.
SAFETY
The Departmental Safely Committee has issued the following guidelines.
1. Experimental work should normally not start before 9.00 am and
should normally finish by 5.00 pm.
2. Should it be necessary to work outwith these hours for short periods
this must be approved by the supervisor and the usual rules of late working
will apply. If the supervisor has to leave before experimental work is
complete written permission must be given and in such cases a designated
proxy ( academic, post-doctoral or senior technical staff) must be present
in the building.
3. Access to IT equipment will be available only when Janitors are
present in the building.
GUIDELINES FOR PRESENTING AND WRITING A THESIS
The thesis counts for 40% of the marks assigned to the project and, in
addition, is the only tangible result of your work which can be shown to
the External Examiners. It is therefore important that you do not let yourself
down by a badly written or produced thesis.
Technical Points
The thesis should be word processed (the Department now has an adequate
number of PC's with WORD 6 installed).
The font should be clear. Fonts normally used are Times New Roman or Arial
(usually 10, 11 or 12 point). This document is written in Arial 10pt. with
main headings in 12 pt bold.
The thesis should use 1.5 line spacing and have a reasonable margin on
the left hand side to allow for binding. (WORD 6 gives default margins
of 3.17 cm left and right and 2.54 cm top and bottom which are acceptable).
Pages should be numbered consecutively, as should diagrams and spectra.
Since the word processor will do the numbering for you, it is easier if
you do not include whole page diagrams or spectra in the page numbering,
but this is a matter of choice.
Chemical structures can be drawn using ChemWindow and copied into WORD
6. On the other hand there is nothing wrong with Xeroxing in structures
(and indeed diagrams) provided that the result looks neat and clear.
References
Referencing work is very important and is frequently badly done. The format
shown in the following examples is that employed by the Royal Society of
Chemistry. It should be used unless your supervisor suggests an alternative.

3. Theses:

Content
The thesis should contain
Title page
Acknowledgements
Contents page (with page numbers)
A one page Abstract
Introduction
Experimental Section,
Results and Discussion (or Results and Discussion as separate sections)
Conclusions
References
The above is the logical order, but in some areas it is normal to put the
experimental section at the end - consult your supervisor.
The INTRODUCTION should set the work in context, review previous work (fully
referenced), describe any techniques or theories with which you were unfamiliar
when you began the research, and describe what you intended to do.
The EXPERIMENTAL SECTION should give full experimental details of all reactions
or experiments carried out. It is particularly important to indicate which
are literature preparations and which are novel. If a literature preparation
is reported it is important to note if you modified it or if it behaved
in an unexpected way. New compounds should be as fully characterised as
possible and it is a good idea to include the actual spectra of new compounds.
The DISCUSSION is extremely important and is often where students do not
do themselves justice. A project where absolutely nothing has worked can
be made interesting by discussing WHY things went wrong. In any case the
discussion is often where you show how much of the project you understood!
The CONCLUSIONS should summarise the work and suggest how it could be continued
in the future.
The ABSTRACT will be similar to the Conclusions but should be concise and
incisive - it is the first thing an examiner will read, and should encourage
him or her to read the rest of the thesis!
Finally: SPELL CHECK YOUR THESIS.

Objectives:
1. Specify the characters of symmetrized and anti-symmetrized
direct product representations and apply them to the characterization of
