Visible bands of divanadium.

Observations in laser-induced fluorescence between 570 and 620 nm with vanadium metal and helium can be assigned to (3)Sigma(u)(-)-X (3)Sigma(g)(-) spectra in the V(2) molecule. Dispersed fluorescence data have been collected and rotational analyses performed.

Electronic spectra of iron monohydride in the infrared near 1.35 and 1.58 microm.

The complex, many-line spectrum of FeH, lying in the infrared region between 5500 and 7500 cm(-1), has been shown to consist of two separate electronic transitions: E (4)Pi-X (4)Delta and E (4)Pi-A (4)Pi. High resolution Fourier transform spectra from thermal emission have been rotationally analyzed in detail. Lambda doubling in both the E (4)Pi and A (4)Pi states is considerable.

The first observation of the rhodium monofluoride molecule: jet-cooled laser spectroscopic studies.

Rhodium monofluoride has been observed and spectroscopically characterized. RhF molecules were produced under jet-cooled conditions in a laser vaporization molecular beam source by the reaction of a laser-vaporized rhodium plasma with SF(6) doped in helium, and studied with laser-induced fluorescence spectroscopy under both medium and high resolution. More than 25 bands have been observed in laser-induced fluorescence between 18,500 and 24,500 cm(-1) and five of these have been recorded at 200 MHz resolution.

Characterization of Electronic Spectra of Rhodium Monohydride and Monodeuteride.

The electronic spectra of rhodium monohydride and monodeuteride, obtained using a molecular beam laser vaporization source, have been investigated from 400 to 500 nm, by laser excitation and dispersed fluorescence spectroscopies. The ground level of RhH is (3)Delta(3) with omega(e) approximately 2040 cm(-1) and omega(e)x(e) approximately 46 cm(-1). The corresponding RhD data are omega(e) approximately 1422 cm(-1) and omega(e)x(e) approximately 18 cm(-1).
