Several rotational transitions of the benzene-HCN dimer have been observed with the Balle/Flygare pulsed beam, Fourier transform microwave spectrometer. They are characteristic of a prolate symmetric top and give preliminary values of 1214.1 MHZ for $B_{0}$ and of 3.97 {\AA} for the c.m. $(C_{6}H_{6})$ to c.m. (HCN) distance. Analysis of the $^{14}N$ hfs finds $\chi_{aa}(^{14}N)$ to be -4.22 MHz, which corresponds to an average projection angele between the HCN and a-axes of 15.2. A sililar, more approximate value of 22 was found for DF in $C_{6}H_{6}--DF.^{1}$ The search for transitions of the benzene--HCN dimer was aided by MMC predictions of the PES and equilibrium $structure,^{2}$ which are in good agreement with experiment. Plans are underway to find and characterize the $Ar_{3}-HCN$ tetramer for comparison with the $C_{6}H_{6}-HCN$ dimmer. |
