✦ Synopsis

The near-infrared emission spectra of the X 2 2 ⌸ 3/2 3 X 1 2 ⌸ 1/2 fine structure transitions of PbF and PbCl have been investigated by high-resolution Fourier-transform spectrometry. Despite the large fine structure splitting, the bands can be equally well analyzed with Hund's case (a) or case (c) formalisms. Accurate rotational constants for the v ϭ 0 vibrational levels of 208 PbF and 208 Pb 35 Cl and hyperfine structure constants for 207 PbF have been derived.

The X(1)(2)Pi(3/2) and X(2)(2)Pi(1/2) potential energy curves of the FO free radical have been determined from a fit to the available high-resolution spectroscopic data. The data set spans the vibrational states v = 0-7 and includes X(2)(2)Pi(1/2) <-- X(1)(2)Pi(3/2) fine-structure transitions. The d

A high-resolution excitation spectrum of gaseous YS has been recorded by laser excitation spectroscopy in a supersonic molecular beam. The YS molecules were produced by the reaction of laser-ablated yttrium atoms with CS 2 . The (0, 0) band of the A 2 P 1/2 -X 2 S / transition near 750 nm was rotati

Observations of the rotational spectrum of BrO have been extended to include vibrational levels up to v ϭ 8 in the X 1 2 ⌸ 3/ 2 and v ϭ 7 in the X 2 2 ⌸ 1/ 2 states. The rotational spectra of isotopically enriched Br 18 O, X 1 , v ϭ 0, 1 and X 2 , v ϭ 0 have been observed as well. The spectra of all
