The rotational spectra in the v 10 = 4 vibrational state of propyne have been determined in the frequency range 17–52 GHz. Molecular constants for this vibrationally excited state have been determined from more than 16 observed rotational transitions. Agreement between experimentally measured frequencies are presented and compared with those calculated using the results of basic perturbation theory. Matrix elements for the diagonal and nondiagonal terms were obtained from a previous paper by A. Bauer, G. Tarrago, and A. Remy. [ J. Mol. Spectrosc. 58, 111–124 (1975)].
