Dipole moment measurements have been made on a series of halophosphines using gas phase heterodyne beat methods. Values obtained are: PF3, 1.00±0.03 D; PF2Cl, 0.93±0.01 D; PFCl2, 0.86±0.05 D; PF2Br, 0.83±0.05 D; and PF2I, 0.85±0.06 D. The value for PF3 is in reasonable agreement with the microwave value [R. G. Schulman et al., Phys. Rev. 78, 145 (1950)], of 1.025±0.009 D. Molecular moments for the mixed halophosphines are approximated reasonably well by the vector sum of P‐X moments, but the value for PF2H cannot be estimated in this way. An explanation is offered in terms of a polarization model
