Geometric isomerization and restricted rotation in iminoxyl radicals from benzaldoximes.

Oxidizes the E geometrical isomers of benzaldoxime, p-chlorobenzaldoxime and p-methylbenzaldoxime to the corresponding iminoxyl radicals within the cavity of an EPR spectrometer by using photolytically produced tert-butoxy radicals. Geometry of iminoxyls at low temperature; Notion of Molecular Orbital theory.
