Introduction
UV-Vis spectroscopy: Beer Lambert’s law, Types of
transition, Concept of auxochrome and chromophore,
factors affecting , Woodward-Fieser rules for calculation of
max in diene systems.
IR spectroscopy: Introduction, types of vibration,
selection rules, Hooke’s law, problem, identification of
functional groups like C-C, C=C, -OH, -NH2 and -C=O.
NMR spectroscopy: Basics of NMR spectroscopy,
chemical shift, Shielding and de-shielding effect, Factors
affecting chemical shift,
Structural elucidation of simple compounds
, What is Spectroscopy ?
Spectroscopy is a technique which concerned with the
study of properties, composition and structure of
matter by interaction with electromagnetic radiation
• Spectroscopic method of
analysis involves the
measurements of the
intensity and wavelength of
radiation.
• This provides the basis for
sensitive methods of
detection and quantitation.
• Involves the use of
equipment, which may be
simple, or extremely
complex, with design
features involving the latest
technological development.
, Absorption spectrum and Emission spectrum
The difference between absorption and emission
spectra are that absorption lines are where light has
been absorbed by the atom thus you see a dip in
the spectrum whereas emission spectra have spikes in
the spectra due to atoms releasing photons at those
wavelengths.
