Abstract
A comparison is made between the corresponding out-of-plane CH deformation modes in the compounds CH2:CMe·CO·OX, CH2:CHCO·OX, and MeCH:CH·CO·OX for nine different substituents X. The results provide reinterpretations of assignments, evidence of interactions between modes of a type in contrast to any expected resonance interactions, and some new considerations of conformational equilibria.Keywords
