The rotational a‐type spectra of the five most abundant isotopomers of HNCSe were recorded in natural abundance. Using Watson's S‐reduced Hamiltonian the rotational and some centrifugal distortion constants could be determined for the ground vibrational state of the various isotopic species. With the aid of these constants the restructure of HNCSe could be refined and the parameter specifying the quasilinearity of the molecule could be estimated.
