RESONANT TWO-PHOTON IONIZATION TIME-OF-FLIGHT MASS SPECTROSCOPY (R2PI-TOFMS) OF JET-COOLED CuGa AND CuIn

Author Institution: Steacie Institute For Molecular Sciences, National Research Council Canada, 100 Sussex Dr., Ottawa, On. K1A 0R6.Diatomic CuGa and Culn produced in a low temperature molecular beam source have been studied using R2PI. For both molecules, four band systems in the $14500 to 27500 cm^{-1}$ range have been identified and analyzed. A system located in the red has been recorded at high resolution using the output of a cw ring dye laser pulse amplified using a four stage amplifier chain pumped by the second harmonic of a Nd: YAG laser. The results of this analysis, which include determinations of vibrational frequencies, bond lengths, ionization potentials and dissociation energies, will be compared with calculation using density functional theory (DFT)
