Measurement and analysis of hyperfine splitting in the microwave spectrum of selenoformaldehyde (CH277Se) has yielded77Se spin-rotation constants, which are compared with constants calculated using the coupled Hartree-Fock technique and with constants of homologous molecules. Rotational and centrifugal distortion constants for CH277Se have been derived from the resultant pure rotational frequencies. An empirical prediction of spin rotation constants has been made for telluroformaldehyde (CH2125Te).
