Laser enhanced chemical reaction studies. Technical progress report, January 1, 1982-October 31, 1984
Experimental studies of dynamic molecular processes are described with particular emphasis on the development of a powerful new infrared diode laser probe technique. This technique allows us to determine the final states of CO/sub 2/ (and other moledules) produced by collisions, photofragmentation, or chemical reactions with a spectral resolution of 0.001 cm/sup -1/ and a time resolution of 10/sup -7/ s. Such high spectral resolution provides a detailed picture of the vibrational and rotational states of molecules produced by these dynamic events. We have used this experimental method to probe collisions between hot hydrogen atoms and CO/sub 2/ and to study the final state energy distribution of CO/sub 2/ produced as a result of photodissociation of pyruvic acid. Infrared and uv fluorescence technique have also been used to investigate collisions between hot hydrogen atoms and CO, CO/sub 2/, CH/sub 3/F; photofragmentation of 1,3,5-triazine; chemical reactions between hot hydrogen atoms and N/sub 2/O; photochemical studies of Br/sub 2/ trapped in rare gas matrices; infrared multiphoton dissociation of C/sub 4/F/sub 8/; and vibrational relaxtion of (COF)/sub 2/. Progress in these interconnected experimental areas is briefly described.
