The microwave spectra of 17OPF3 and 33SPF3 were investigated by Fourier transform microwave spectroscopy and the 17O and 33S quadrupole coupling constants were determined. The 17O coupling constant is compared with several others from related phosphine oxides to characterize the π-bonding in these systems.
