Can you use infrared spectroscopy to differentiate between methyl chloride and chloroform? Use a symmetry analysis (using a reducible representation) to determine how many IR active molecular vibrations each molecule possesses. For this analysis, consider only the C-H vibrations; you can treat the -CCl_n portion of each molecule as one “atom”.

Explain (in your own chemically accurate words) why and how you can use IR spectroscopy to measure bonding parameters for a polar, diatomic molecule. You will need to address why the ro-vibrational spectrum is in the IR region of the electromagnetic spectrum (this may include a discussion of vibrational and rotational motion and the selection rules associated with them) the origin of the P, Q and R branch (including a figure to indicate the origin of each set of peaks...
