Detection and Study of Molecular Species Using Time Resolved Laser Spectroscopy

摘要

The detection of trace components in the atmosphere and contaminants or other active agents in or on support facilities is of primary importance to the protection of military personnel. One proposed approach relies upon the decomposition of the agent followed by the detection of characteristic fragments. This allows highly sensitive, remote spectroscopic techniques to be used for the analysis. In the design of propellants, it is important to be able to characterize and study their primary decomposition products. This also creates a need for the remote detection of molecular fragments, many of which are not well studied chemical species. The purpose of this basic research effort will be to identify and characterize small molecular fragments formed from the decomposition of model compounds. It is hoped that the results of such research will form the genesis for nondestructive, quantitative analysis methods under field conditions requiring either remote or point sensing.
