✦ Synopsis

Abstract

The pure rotational Raman spectrum of selenium trioxide monomer in the vapour phase at 410 K has been obtained and analysed for the first time. The following rotational constants and bond lengths were obtained:
This is the first spectroscopic determination of r~0~ in SeO~3~. The precision of r~0~ is significantly greater than the value of r~a~ = 169±1 pm obtained from an earlier electron diffraction study.

The Fourier transform microwave (FTMW) spectra of gaseous monomeric AuF, AuCl, and AuBr have recently been reported (1, 2). Among other things, equilibrium geometries were evaluated, as well as several hyperfine parameters. The Au nuclear quadrupole coupling constants (NQCC) were found to show a mar

The broadening is found to be characteristic of the foreign gas and is interpreted in term of
