Recent projects in our group have included laboratory work on the fluroethanes(project A)and molecular dynamics work on the methane/perfluromethane(project B). The data collection on (A) is complete. Two different normal coordinate line shapes were examined from the probe (1,1,1-trifluroethane). The A mode from the C-H stretch and the A mode from the C-F stretch were recorded. Then a fast FT procedure was carried out and the time correlation functions were obtained from each signal. A discussion of early results will be presented. In the (B) system, the machine experiments using the CHARMM algorithim on 1000 enties is in the process of being carried out. A brief review of the experimental work leading up to the purpose of this calculation will be carried out. Some MD results may be available.
