The spectrum of propylene oxide was collected from 70 GHz to 1 THz using direct absorption millimeter and submillimeter spectroscopy. Analysis of the spectrum was performed using the SPFIT/SPCAT programs for the A state. A full internal rotor analysis was performed using the XIAM program. The barrier to internal rotation of the methyl group was determined to be 893 cm^(−1). The precision of the rotation constants, centrifugal distortion constants, and internal rotor parameters was increased over the results reported by previous low-frequency studies. The results of this laboratory study and the associated analysis, as well as a spectral prediction for the ground vibrational state of propylene oxide, are presented.
