Abstract:

An excimer laser system capable of producing high-intensity laser radiation in the ultraviolet spectra region has been acquired and is being used for studies of the spectroscopy and collision dynamics of a number of important transient molecular species of importance in the flame chemistry of potential fire suppressant agents. In particular, the excimer laser was employed for the photolytic preparation of transient species of interest. Spectroscopic investigations of several iron-containing molecules, including FeCl, FeO, and FeNC, have been carried out. A study of collisional electronic quenching and vibrational energy transfer of the excited CFAexp 2Sigma molecule in collisions with a number of atomic and molecular colliders has been carried out. The electronic spectroscopy of the PO2 radical, prepared in a rotationally cold supersonic beam, has also been investigated.
