Infrared Cavity Ringdown Laser Absorption Spectroscopy: Metal-Containing Clusters and HEDM Molecules

摘要

Efforts focused on four activities related to the central objective of studying metal-containing clusters, HEDM molecules, and clusters of ceramic materials. Nineteen AFOSR supported papers were published on the following topics (including five journal cover articles) : 1) Development of high resolution (100 MHz), high sensitivity pulsed infrared cavity ringdown spectroscopy as a general tool for trace species characterization. 2) Infrared cavity ringdown system with medium (900 MHz) resolution constructed and operational. 3) IR studies of hydrogen bonding in water, methanol, ethanol, and butanol clusters carried out. 4) More difficult IR experiments on laser vaporized carbon and silicon carbide initiated.
