SA quite different approach (Biirgi and Dunitz, 1983), using atomic vibration tensors to estimate torsional energy barriers (assumed sinusoidal) about single bonds, is described by Trueblood and Dunitz (1983) and has been applied to pseudo-Jahn-Teller deformations of octahedral complexes by Stebler and Biirgi (1987).
