This research looks at the effect of inert environments on the structures of pyridine-SO2 complexes. These effects were able to be observed both experimentally through low temperature FTIR as well as computational models. Experimental FTIR data illustrates environmental effects through measured vibrational frequency shifts between the fragments and the complex. Computational models provide detailed structural information as well as predicted frequencies that can be compared to experimental data. At this point we have observed the spectra of both pyridine-SO2 and 3,5-Difluoropyridine-SO2 in solid Ne at 6K, and we note no difference between most of these data and the predicted values. The exception is the SO2 asymmetric stretching vibration, and the discrepancy here may indicate a solvent effect on the structure, or a failure of the theory to accurately predict the gas-phase structure. In the 3,5-Difuoropyride-SO2 spectra, this peak is observed at a slightly higher frequency, consistent with a weaker interaction upon addition of the fluorenes. Collection and analysis of spectra in solid N2 are in progress.
