Several CrS transitions bands in the near infrared region have been observed using the technique of laser vaporisation/reaction with supersonic expansion and laser induced fluorescence (LIF) spectroscopy. Preliminary analysis shows that these bands are vibrational sequence bands of a $\Delta \Omega =0$ transition from $\Omega =-1$ sublevel. Rotational analysis of these bands give molecular constants of the $\Omega =-1$ sublevel. Spectroscopic properties of the low-lying electronic states have been obtained using ab initio calculation. Results of our experimental work and calculation will be presented in the meeting.
