✦ Synopsis

The (0, 0), (1, 0), (2, 0), (3, 0), and (4, 0) bands of the C 3 ⌬-X 3 ⌬ transition of TiS, between 743-863 nm, were studied using the technique of laser vaporization/reaction with supersonic cooling and laser-induced fluorescence (LIF) spectroscopy. The linewidth of the LIF spectrum obtained was about 250 MHz. The P, Q, and R branches of each ⌬⍀ ϭ 0 subband were observed. A merged least-squares fit of the measured line positions yielded molecular parameters of the v ϭ 0 -4 levels of the C 3 ⌬ state and the v ϭ 0 level of the X 3 ⌬ state.

Rotational analyses of 32 subbands of the near-infrared 3 ⌽ 3 (1) 3 ⌬ system of LaF have been carried out, involving the levels v ϭ 0 -7 of the two states. The three subsystems were first treated as separate singlet systems, directly at equilibrium. Perturbations were revealed in the lower state, as

The near-infrared absorption spectra of the FeC radical have been measured by diode laser spectroscopy in the regions from 11 810 to 13 200 cm -1 . Rotationally resolved 28 new vibronic bands of the 56 Fe 12 C major isotopic species were observed as well as two known bands. Five of them were assigne
