The microwave spectrum of argon-phosphorus trifluoride
Abstract
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), DJ = 3.53(1), DJK = 60.4(1) and d1 = -0.240(7). The argon atom is 3.953 Å ( rc.m.) from the PF 3 center of mass and rc.m. makes an angle of 70.3° with the C3 axis of the PF 3.
