Abstract: | The fundamental vibration-rotation band of SH (X2Π) has been studied in absorption at Doppler-limited resolution with an estimated accuracy of 0.002 cm?1. The band origin (ν0 = 2598.7675 ± 0.0003 cm?1) and the molecular constants for the excited vibrational state (v = 1), as well as improved molecular constants for the ground vibrational state, have been determined in a least-squares fit. |
