Abstract

The far infrared spectrograph at The Ohio State University was used to obtain the spectra of phosphine and arsine molecules. Tabular and graphical data show series of lines for phosphine, deuterated phosphine, arsine, and deuterated arsine in the ground vibrational state. Two previously unpredicted series of lines are clearly shown in the spectrum of phosphine and indicated in that of arsine. These additional series are ascribed to rotational transitions occurring while the molecules are in excited vibrational states and their rotational constants as well as the equilibrium rotational constants have been computed.
