Application of Spectroscopic Methods in Molecular Structure Determination

By Prof. Sankararaman   |   IIT Madras
Chemists are molecule makers.  Whenever a new molecule is synthesized it is essential to determine its structure using spectroscopic techniques.  This course is all about practical applications of spectroscopic methods for the determination of organic molecules.


INTENDED AUDIENCE: BSc Chemistry final year, MSc Chemistry and PhD Chemistry students.

PREREQUISITES       :         A good background knowledge in organic chemistry/stereochemistry necessary

INDUSTRY SUPPORT :    Scientists in Chemical and Pharma industry will be interested. Beneficial to scientists working chemistry in R&D labs, national labs etc
 

Learners enrolled: 1856
