2/CH/A
Analytical Chemistry
Unit description
The aim of this unit
To provide an introduction to the range of spectroscopic analytical techniques used for structure
determination in organic chemistry and to develop the skills needed to interpret such spectra. Also to
acquaint students with the techniques of atomic adsorption, electronic spectroscopy, infrared
spectroscopy, electrochemical and thermal methods of analysis and the use of X-ray methods in an
analytical context, together with the associated theoretical background.
Learning outcomes
Students should be able to interpret UV, IR, NMR and MS data in the elucidation of the structure of
relatively complex organic molecules. They should be able to select appropriate analytical techniques to
use in order to solve a given problem, appreciate the principles behind the above analytical methods and
should be able to solve appropriate level problems based on analytical data supplied to them.
