The argon-PF 3 complex has been prepared in a supersonic expansion of Ar (98%) and PF 3 (2%). A Fourier-transform micro-wave spectrometer employing a Fabry-Pérot cavity was used to assign 28 rotational transitions. The rotational constants (MHz) and distortion constants (kHz) were A = 7332.468(10), B = 1023.055(2), C = 952.564(2), D J = 3.53(1), D JK = 60.4(1) and d 1 = −0.240(7). The argon atom is 3.953 Å ( r c.m.) from the PF 3 center of mass and r c.m. makes an angle of 70.3° with the C 3 axis of the PF 3.
