Abstract : Two experimental investigations have been started during the first contract period, October and November 1985. The first of these involves laser induced fluorescence (LIF) of the CF radical in its ground state via the transition near 233 nm. A discharge flow system has been set up in lithium fluoride (LIF) cell, so that a microwave discharge of carbon fluoride/argon (CF4/Ar) mixtures an be used to prepare the radical: laser output near 233 mm has been generated by Raman shifting the output of a pulsed neodymium YAG pumped dye laser. Some fluorescence has been seen: the experimental sensitivity is presently being improved, and computer simulation of the expected spectrum is being carried out.
