Module Overview

Physical and Organic Spectroscopy

The purpose of this module is to provide the learner with a detailed understanding of specific areas of spectroscopy in particular physical and organic spectroscopy. The physical spectroscopy element consists of a more advanced treatment of rotational, vibrational and electronic spectra with particular emphasis on the origin and underlying principles. The theoretical aspects are underpinned by suitably chosen experiments which amplify and reinforce the lecture material.
The organic spectroscopy element consists of mass spectrometry, IR, 1H NMR and 13C NMR. A particular focus will be placed on integrated problem solving. The laboratory element will involve integrated problem solving workshops for structure elucidation.
