Module 1: Fundamentals of Spectroscopy

Module 1: Fundamentals of Spectroscopy Mod. #1-1 MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Chemistry Introduction to Experimental Chemistry Module 1: Fundamentals OF Spectroscopy It s amazing how much we can learn about molecules and materials by shining light on them! In Spectroscopy , we use light to determine a tremendous range of molecular properties , including electronic , vibrational, rotational, and electron and nuclear spin states and energies. From this information, we can often deduce a great deal of additional insight, including: Molecular identities what is the sample composed of? Molecular conformations, geometries, and sizes Chemical equilibria Effects of liquid or solid-state surroundings on molecules Dynamics, including the rates of chemical reactions, interchange among different molecular conformations, relaxation of molecular excited states, photosynthetic energy transfer, protein folding, etc.
