ORIENTATION DEPENDENCE OF CHEMILUMINESCENCE SPECTRA OF CF3 FORMED IN THE REACTION OF ORIENTED CF3H WITH AR(P-3)

Chemiluminescence of the CF3* radical formed in the reaction of Ar(3P) with the oriented CF3H was taken at five different wavelengths in the range from 500 to 700 nm for two reactant orientations with a reference orientation. A remarkable alignment dependence of the emission spectra was observed. Analysis of the wavelength dependence of the CF3 chemiluminescence revealed the existence of three reactive sites due to two reaction mechanisms. One is preferable at the side-on orientation and the second is both at the CF3 end and H end orientations.
