✦ Synopsis
High-resolution Fourier transform spectra of the laser-induced fluorescence of copper dichloride produced in a free-jet expansion are presented. The supersonic molecular beam produces rotational cooling and a nearly collisionfree environment. Dispersed fluorescence spectra are found to be free of the continuum which restricted the data obtainable with a classical source (hot cell). The reduction in thermal emission allows the fluorescence to be recorded from the laser line (585 nm) out to 1.3 mm, revealing many new vibrational levels of CuCl 2 in its ground electronic state, X ˜2P g(3/2) .
