✦ Synopsis

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 determinable spectroscopic constants provide an excellent description of the equilibrium properties of both the X(1) and X(2) states in addition to the vibrational dependence of the spin-orbit coupling constant. The experimental properties of FO are used to evaluate the performance of different ab initio methods for describing the F-O bond. Copyright 2001 Academic Press.

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

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)

We report new potential energy curves for the X 1 + and A 1 states of the CO molecule by employing the realistic extended Hartree-Fock approximate correlation energy model for diatomics with inclusion of the united-atom limit (EHFACE2U). Special care has been taken to describe the A 1 potential maxi
