Abstract

Dynamics and inertia: The rotation of the CF 3 top in α,α,α-trifluorotoluene becomes considerably hindered by a V 3 barrier in α,α,α-trifluoro-p-tolualdehyde. Situated in a local V 6 environment, the V 3 barrier is caused by the aldehyde group and communicated through the aromatic π system. Quite dramatically, the ground state inertial defect jumps from -1.271 to -89.961 uÅ 2, thus reflecting the electronically induced rigidity (see figure).
