Abstract
Jet-cooled laser induced fluorescence spectra of HSiCl, DSiCl, HSiBr, DSiBr, HGeCl, and DGeCl have been obtained by diluting appropriate trihalosilane or germane precursors with argon and expanding them through a pulsed electric discharge. The upper state harmonic frequencies, anharmonicities, and isotope shifts were obtained from detailed vibrational analyses of the spectra. In favorable cases, the $\theta^{0}_{0}$ bands were recorded at $0.05 cm^{-1}$ resolution and rotationally analyzed, providing ground and excited state rotational constants. The vibrational and rotational data have been used to obtain ground and excited state structures and upper state harmonic force fields for these reactive intermediates.
