✦ Synopsis

The G0 / u (6 1 P 1 ) -X 0 / g excitation and fluorescence spectra of Hg 2 van der Waals molecules, produced in a pulsed free-jet supersonic expansion beam crossed with a pulsed dye-laser beam, were studied using Ar as the carrier gas. A well-resolved vibrational structure of the G0 / u R X 0 / g excitation spectrum was recorded, as well as the isotopic structures of the vibrational components. A Condon internal diffraction pattern in the G0 / u r X 0 / g fluorescence band, emitted upon the selective excitation of the £ Å 39 vibrational component, was also observed and confirmed the assignments derived from the analysis of the isotopic structure. Analyses of the spectra yielded molecular constants for both states, as well as information on the ground state potential energy curve. The results are compared with those obtained from other experiments and from theoretical calculations.

The high resolution, rotationally resolved laser induced fluorescence spectra for the A2A1 left and right arrow X2E transitions of CF3O and CF3S were recorded. In addition to the origins, the symmetric vibrational band 301 and the nontotally symmetric bands 501 and 601 were analyzed for CF3O, while
