Direct infrared absorption of clusters in pulsed molecular beams: Second progress report, August 1, 1987-July 31, 1988

This report describes accomplishments over the past year in research supported by this grant, and also outlines plans for the next year. The principal goal for future work is the continued development of a new molecular beam infrared absorption spectrometer, and the application of this instrument to the study of cluster molecules of atmospheric importance. Results presented here demonstrate that the infrared instrumentation is currently a productive apparatus. However, work in progress, to be described in this report, will substantially improve the sensitivity of the basic experiment. In addition, initial work on a new experiment will be discussed.
