Electron diffraction studies of hot molecules. III. Stretching and bending anharmonicity in CF3Cl

Bond lengths, amplitudes of vibration, and asymmetries in distribution of nonbonded atom pairs were determined for CF3Cl at temperatures ranging from 300 to 1220 K. The CF but not the CCl bond length followed the commonly invoked approximation Δr=(3a/2)Δl2+ΔK+Δδr. The coefficients of skewness of nonbonded radial distribution peaks revealed substantial bending anharmonicity comparable to that detected in a previous study of binary fluorides and accounted for by the valence‐shell‐electron‐pair repulsion force field in its points‐on‐a‐sphere representation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70035/2/JCPSA6-80-9-3923-1.pd
