Abstract: | The emission spectrum of the SeO molecule excited in a microwave discharge and recorded at low resolution revealed the existence of a brief band system in the near-infrared region 6470-5560 cm?1. The system consists of five bands divided into two groups which were assigned as the Δv = 0 and +1 sequences of the transition a2-X21 (X being the case ?c3Σ? ground state). An approximate value of the rotational constant B0 of state a was obtained from the observed separation between the Q and R heads of the 0-0 band and the known value of B0 of state X. The derived molecular parameters of state a are: ν00 = 5566.2 cm?1, , B0 = 0.456 cm?1. |
