Tin metal has been laser ablated with the pulsed fundamental output of a Nd:YAG laser. Chlorine gas dissolved in argon was pulsed into the products of this ablation event. One outcome of this has been the formation of SnCl entrained in a supersonic expansion. The expansion occured between the horn antenna of a chirped pulse, Fourier transform microwave spectrometer and accordingly the pure rotational spectra of SnCl, X² _r, has been recorded for the first time between 8 and 18 GHz. Spectroscopic constants will be presented.
