Short Time

We have obtained A-band absorption resonance Raman spectra of 1-chloro-2- iodoethane in cyclohexane solution. We have done preliminary time-dependent wavepacket calculations to simulate the resonance Raman intensities and absorption spectrum in order to learn more about the short-time photodissociation dynamics. We compare our preliminary results for 1-chloro-2-iodoethane with previous resonance Raman results for iodoethane and find that there appears to be more motion along non- C—I stretch modes for 1-chloro-2-iodoethane than for iodoethane. This is consistent with results of TOF photofragment spectroscopy experiments which indicate much more internal excitation of the photoproducts from 1-chloro-2-iodoethane photodissociation than the photoproducts from iodoethane photodissociation.

Heat Of Dissociation

In some previous papers it has been shown by the author and others that saturated compounds of most substances in the vapour state show continuous absorption. A typical example is SO 3 -vapour, which was recently studied by the author and which enabled him to make an accurate estimation of the heat of dissociation of oxygen. In the present work, the absorption spectrum of N 2 O was investigated with a view to determining the heat of dissociation of nitrogen. Leifson was the first to investigate the absorption spectrum of N 2 O gas and found that the gas shows no selective absorption in the Schumann region. He states that the absorption is in the form of two continuous bands, the first extending from λ 2000 to λ 1680 and the second from λ 1550 beyond the range of observation. Recently Wulf and Melvin showed that when N 2 O is illuminated with light of wave-length λ 2300, it is decomposed photochemically into NO and N; they also noticed that N 2 O possesses no band absorption.
