Freshman Organic Chemistry II (CHEM 125B)Spectroscopic determination of bond dissociation energies is relatively straightforward for many diatomic molecules, but for polyatomic molecules it requires merging the results from a variety of challenging experiments. Professor Ellison describes how such techniques as flowing-afterglow mass spectroscopy and negative-ion photoelectron spectroscopy together with data on free-radical kinetics and heats of formation have allowed precise determination of the O-H, C-H, and C-O bonds in methanol and other compounds. Interpreting these reliable data provides new insight into the nature of chemical bonding and "resonance".0000 - Chapter 1. Diatomic Bond Dissociation Energy from Spectroscopy0128 - Chapter 2.
