About the Course
Spectroscopic methods of analysis are based on the consequences of the interaction of radiation with matter. Spectroscopic methods course deals with the concepts based on the nature of matter and the type of interaction involved. It is divided into five blocks. Blocks 1 and 2 deal with molecular systems and are titled as ‘Molecular Spectroscopic Methods-I’ and ‘Molecular Spectroscopic Methods-II’, respectively. The first of these deals with absorption and scattering of radiation while the second covers methods based on emission of radiation. Blocks 3 and 4 deal with atomic systems and are accordingly titled as ‘Atomic Spectroscopic Methods-I’ and ‘Atomic Spectroscopic Methods-II’ respectively. Block 5, i.e. the last block, is titled ‘Miscellaneous Methods’ and covers the nuclear magnetic resonance and mass spectrometric methods. We would like to mention here that though mass spectrometry is not a type of spectroscopy, yet it is included in the course as it is one of the important techniques of structural elucidation. Needless to say that it is an integral part of analytical methods. All the units covered in these blocks deal with details of principles, instrumentation and the applications of the techniques described.

Block 1 : Molecular Spectroscopic Methods-I
The first block of the course deals with the spectroscopic methods based on the interaction of ultraviolet and infrared radiation with molecules. There are four units in this block.
Block 2 : Molecular Spectroscopic Methods-II
This block deals with the spectroscopic methods of analysis arising out of the interaction of radiation with molecular systems and is based on the emission of radiation by the excited molecular species. There are two units in this block.
Block 3 : Atomic Spectroscopic Methods-I
This block deals with the consequences of interaction of radiation with atoms in the vapour phase in order to analyse them qualitatively as well as quantitatively. It includes Flame Photometry and Atomic Fluorescence Spectrometry.
Block 4 : Atomic Spectroscopic Methods-II
This block discussed the principles and applications of two important analytical methods based on atomic spectroscopies viz., Atomic Absorption Spectrophotometry, Atomic Emission Spectrometry and their applications. These concern the absorption of radiation by the analyte atoms in ground state and the emission of radiation by thermally excited atoms.
