Abstract
A simple design for a heated nozzle, having the capability of reaching approximately 1200k will be presented. This nozzle, in conjunction with a free jet experimental eppearatus, has been used to produce radical species which are subsequently probed by the trechnique of fluorescence excitation spectroscopy. The discussion will focus on two particular radical species, $CF_{2}$ and CFBr for $CF_{2}$, the rotationally resolved first excited state fluorescence lifetimes will ber addressed. The CFBr radical has been utilized as a presursor in the dynamical study of the photodissociation reaction producing CF and Br.
