Abstract

In response to recent interests in laser applications to monitoring the role of radical species in combustion and atmospheric chemistry several new techniques have been developed. In this paper we discuss a laser-pump laser-probe technique utilized in our lab to obtain spectroscopic data for such in situ or long range studies and kinetic data on mass transport, vibrational and rotational relaxation, and chemical decay. The work utilizes a pulsed photolysis (excimer, YAG, CO2) laser to generate the radical in a well defined spatial region and a second probe (tunable dye) laser delayed in time. Applications of this technique to relaxation processes in CF2 and to new spectroscopic data on OCH3 will be discussed.
