CHEM2310 Chemical Spectroscopy

This module is not approved as a discovery module

Module summary

The module includes lectures, workshops, tutorials and assessed coursework, aimed at extending understanding of the theory, and application of NMR spectroscopy and associated analytical techniques, including x-ray crystallography. The shape and symmetry of molecules is important in determining the appearance of the data derived from these techniques and hence it is logical to also discuss molecular symmetry in this module.

Objectives

On completion of the module, students should be able to:
- use 1H, 13C NMR, IR and mass spectrometry in combination in the determination of organic compounds;
- understand the principles underlying NMR spectroscopy;
- appreciate the important of molecular symmetry and symmetry elements;
- understand the principles behind X-ray crystallography.

Learning outcomes
Students will develop analytical skills, critical thinking and problem solving abilities.


Syllabus

Principles of NMR: magnetic fields and nuclear spin; radiofrequency pulses and magnetization; relaxation; pulse sequences to measure relaxation times; chemical shift; the origin of resonance splitting

Applications of NMR: Revision of level 1: chemical shift tables and basic multiplets; second order effects; advanced multiplet analysis, the Karplus equation; Other nuclei: 13C, DEPT etc; Other nuclei: inorganic examples; 2D NMR; Advanced NMR techniques: NOE and NOeSY

Mass spectrometry: Techniques; accurate mass and isotope patterns; Advanced MS

Symmetry: From symmetry to maths – why bother with group theory? Classification of molecules according to symmetry. Symmetries of molecular vibrations, orbitals and allowed transitions.

Private study

Students will need to prepare for tutorials and provide written work in advance of these. The new element to the module is the coursework component . Students will need to read around the subject matter in advance of completing the exercises. While they will be guided as to where to find material they will work through this independently.

Opportunities for Formative Feedback

This will be through in course questionnaires and through setting and marking of tutorial work.
