Abstract
The chemical shift (H-3) of crotonaldehyde complexed by a Lewis acid provides a measure of its strength as a catalyst. A theoretical justification was highly desirable and is provided here: the experimental method works because of the linear dependence of the H-3 chemical shift on the energy of the lowest π * MO in the complex
