 Title: NEAR INFRARED LASER SPCTROSCOPY OF CrS Creators: Shi, Qiang; Ran, Qin; Tam, W. S.; Leung, J. W.- H.; Cheung, A. S.- C. Issue Date: 2000 Publisher: Ohio State University Abstract: 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.
