Two-color multiple-photon dissociation of CF3T

摘要

ective multiple photon dissociation of CF$-3$/T in CF$- 3$/T/CF$-3$/H mixtures by two infrared irradiation fields was studied. An extensive parametric study was done to determine the effect of wavelength and fluence of the laser field and temperature and pressure of the gas. The best results were obtained with irradiation by two closely space laser lines in the 9P branch. Under these conditions, isotopic selectivities exceeding 20000, combined with yields per pulse greater than in single frequency experiments were observed.
