## Abstract The hindered rotation in cubic fields of various shapes and intensities is studied. The βDevonshire Modelβ is extended to include cubic fields being linear combinations of spherical harmonics of order four and six. In contrast to Devonshire's potential, this two parameter manifold of po
Rotational barriers of the dimethylamino group in different enamino aldehydes and ketones have been applied for evaluation of their conformation. It has been maintained that repulsion between bulky substituents causes twisting of the molecule rather than planar deformations. Arguments for and again
