✦ Synopsis

Using a pulsed molecular beam microwave Fourier transform spectrometer, we measured the rotational spectrum of the 1.2 -difluorobenzene-argon van der Waals complex in the range from 7 to (18 \mathrm{GHz}). The rotational and centrifugal distortion constants were found to be (A=) (1373.49072(9) \mathrm{MHz}, B=923.31007(10) \mathrm{MHz} . C=831.07477(6) \mathrm{MHz}, \Delta_{j}=2.1104(8) \mathrm{kHz}). (\Delta_{\mathcal{K}}=2.372(3) \mathrm{kHz}). (\Delta_{\mathrm{K}}=-1.911(3) \mathrm{kHz}, \delta_{j}=0.4744(4) \mathrm{kHz}), and (\delta_{K}=1.785(9) \mathrm{kHz}). The argon atom is placed 3.543 A above the ring plane. ic. 1993 Academic Press. Inc.
