R. Bocquet et al., THE SUBMILLIMETER-WAVE ROTATIONAL SPECTRU M OF OCSE, Journal de chimie physique et de physico-chimie biologique, 90(9), 1993, pp. 1627-1630
The rotational spectrum of (OCSe)-Se-80 has been measured between 600
GHz and 900 GHz. Accurate values of the rotational constant and of the
quartic and sextic centrifugal distortion constants have been derived
.
