✦ Synopsis

Dispersed fluorescence spectra in the spectral range 475-575 nm and fluorescence excitation spectra in the range 2 2 + • 13 34 • • • 410-480 nm were recorded for the A H -X II system of CS 2 and as C-and S-motoplc speoes Based on a u g • • 13 34 ..... 2 comparison of the relative extents of C-and S-Isotopic shifts, new assignments for Fermi polyads of the X Hg state were derived; they are consistent with recent variational Renner-Teller calculations by Brommer and Rosmus based on three-dimensional potential energy functions derived from ab initio calculations. According to an analogous argument, the vibronic levels of the A2IIu state are assigned based on observed ~3Cand 3as-isotopic shifts.

Laser induced fluorescence of a fast ion beam has been applied to 13 CO / 2 for its (0, 0, 0) A ˜2P u -(0, 0, 0) X ˜2P g UV electronic transition. The high resolution (0.005 cm 01 ) of the FIBLAS method, due to a highly reduced Doppler broadening, allows us to evaluate the isotopic shift, to appreci

Spectroscopic investigations of \(\mathrm{CuCl}_{2}\) in its electronic ground state have been extended to transitions to the levels of the \(\left(02^{\prime} 0\right)\) vibronic multiplet. These transitions appear as weak \(P, R\) rotational lines in laser-induced fluorescence spectra recorded in
