✦ Synopsis

The yttrium monochloride molecule (YCl) has been produced in an electric furnace in a DC discharge tube containing YCl 3 powder and argon gas. Triplet transitions of YCl have been observed and identified for the first time in the emission spectrum and studied using LIF (laser induced fluorescence) techniques. High resolution laser excitation spectra have been recorded in the region 12 200-13 100 cm 01 , using a cw single-mode Ti:sapphire laser. The triplet transition centered at 12 789 cm 01 has been rotationally analyzed and assigned as the d 3 F-a 3 D transition; molecular constants have been determined. The X 1 S / Ç a 3 D separation has been investigated by detection of the D 1 P-a 3 D intercombination transition induced by the Ar / 4579 A ˚laser line.

The molecular ion TiF+ has been observed for the first time using high-resolution spectroscopy. The ions were produced in the positive column of an AC glow discharge with a gas mixture of He/TiF4. A single-mode cw dye laser along with the velocity modulation detection technique was used to record an

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 laser absorption spectrum of the TiCl / molecular ion has been observed for the first time in a hollow cathode discharge. The discharge was driven at 25 kHz at powers in the 80-100 W range. Flowing samples of TiCl 4 in Ar were discharged. A total of 235 lines of the 48 Ti 35 Cl / [17.9] 3 D-X 3
