CHM 402: Applications of Modern Physical Methods (4)

Prerequisites (Desirable): CHM 301, CHM 302

Learning Objectives:

Characterization techniques are central to synthesis of inorganic molecules. This course discusses applications of multinuclear NMR, ESR, CV, and XPES which are universal tools to investigate the structure of new molecules. In addition the course also sheds light on thermal methods namely DSC and TGA which are widely used to characterize the thermodynamic properties of solids.
