Objectives On the completion of this subject students will know the basic ideas and terminology of spectroscopy and chromatography; understand the various ways that instruments used in UV/VIS, atomic absorption and optical emission spectroscopy are put together and the purpose of each component; be able to calculate results and prepare samples, and understand the principle of the way the analytical signal is generated, the general properties and the likely interferences; have studied the infrared and Raman spectra of relatively simple polyatomic molecules; have gained an insight into the nature of such molecular species from their spectra, and understand (in an overview sense) how such spectra arise and may be experimentally obtained; recognise and understand the principles of separation of components using partition, adsorption, ion exchange and gel permeation chromatography and understand the operation of modern gas and liquid chromatographs and be able to perform simple analyses using these instruments; have been introduced to the technique of nuclear magnetic resonance (NMR) spectroscopy from the point of view of its range of uses, underlying theoretical principles, instrument design and sample handling factors, spectral parameters, chemical and biological applications, and (in an overview sense only) its potential scope.
Synopsis This subject is designed to introduce the student to the principles of modern instrumentation which are basic to studies in physical, chemical and biological sciences. It is designed around instrumental applications and relevant basic theory. After a general introduction, such spectroscopic techniques as UV/VIS, atomic absorption, infra-red and nuclear magnetic resonance and various aspects of chromatography are covered. The emphasis is on spectral identification, quantitative and qualitative analysis. The subject is taught in the internal mode by lectures and practical activities. For distance education students, detailed study guides are provided and a four-day vacation school applies for practical laboratory work.
Assessment Theory component (examinations and assignments): 74% * Practical work (13 laboratory exercises and written reports): 26%
