[Spectroscopic and chromatographic studies on photochemical isomerism of alpha, beta-diunsaturated ketones].
Spectroscopic (UV, IR, NMR, MS) and chromatographic (HPLC, GC) investigations show for alpha,beta-diunsaturated ketones with one double bond fixed in a cyclohexene-, furan- or thiophene ring in most examples a photochemical Z/E-isomerization in solution by the influence of light. Investigations of conformers by IR and NMR however are not influenced during usual operations and light protection is not nessessary.
