Van der Waals potential energy surface of CH2ClF center dot center dot center dot Xe
The rotational spectra have been assigned for six isotopologues of the CH2ClF center dot center dot center dot Xe, arising from some combinations of the Cl-35, Cl-37, Xe-129, Xe-131, Xe-132 and Xe-134 isotopes of Cl and Xe. The xenon atom is located out of the ClCF plane, interacting with both F and Cl atoms. All rotational transitions are split in several component lines, due to the Cl-35 or Cl-37 (or Xe-131) quadrupole components, and to the tunneling motion of the Xe atom between two equivalent positions, below and above the ClCF plane. The barrier between these two equivalent conformations is ca. 76 cm(-1). (C) 2008 Elsevier B. V. All rights reserved.
