The microwave spectrum of the van der Waals complex CF3Cl-Ar has been investigated by pulsed jet Fourier transform microwave spectroscopy. The observed spectra of the 35Cl and 37Cl isotopologues are typical of asymmetric tops, with rotational constants A, B, C = 3373.118(4), 988.2529(4), 879.5788(3) and 3286.66(4), 985.50(3), 871.359(8) MHz, respectively. The Ar atom is almost "L-shaped" with respect to the Cl-C bond, at a r0 distance of 3.824(2) Å from the center of mass (CM) of CF3Cl and with the angle Cl-CM-Ar = 81(2)°. The dissociation energy has been estimated to be 2.3 kJ mol-1.

Abstract
The microwave spectrum of the van der Waals complex CF3Cl-Ar has been investigated by pulsed jet Fourier transform microwave spectroscopy. The observed spectra of the 35Cl and 37Cl isotopologues are typical of asymmetric tops, with rotational constants A, B, C = 3373.118(4), 988.2529(4), 879.5788(3) and 3286.66(4), 985.50(3), 871.359(8) MHz, respectively. The Ar atom is almost "L-shaped" with respect to the Cl-C bond, at a r0 distance of 3.824(2) Å from the center of mass (CM) of CF3Cl and with the angle Cl-CM-Ar = 81(2)°. The dissociation energy has been estimated to be 2.3 kJ mol-1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
