Laser-excited fluorescence of CSCl2

Resonance fluorescence spectra of the $\text{A}\text{?}{}^1\text{A}{}_2\text{→}\text{X}\text{?}{}^1\text{A}{}_1$ system of CSCl₂ are excited by an Ar⁺ laser operated at 5145 Å. The radiation is selectively absorbed by the 2₀¹3₀¹4₀¹ transition of the ³⁵Cl₂CS isotope. About 55 fluorescence bands have been measured and assigned, and the vibrational constants of the ground state have been calculated from the observed displacements.
