The parameter values differ slightly from those in (1). The data set is somewhat limited, but should be sufficient for observations in cold sources. Low-K transitions should be viewed with caution above J = 12. Transitions with Ka exceeding one should be viewed with increased caution.
At low temperatures, it may be necessary to discern between ortho-c-H2C334S and para-c-H2C334S. The ortho and para states are described by Ka odd and even, respectively. The nuclear spin-weights are 3 and 1 for ortho-c-H2C334S and para-c-H2C334S, respectively. The JKaKc = 111 level is the lowest ortho level. It is 1.1891 cm–1 above ground.
The dipole moment is from a quantum chemical calculation in (1).
