Abstract
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.
摘要
光谱（紫外、红外、核磁共振、质谱）和色谱（高效液相色谱、气相色谱）研究表明，在大多数情况下，对于双键固定在环己烯、呋喃或噻吩环中的α,β-不饱和酮，在光的影响下，溶液中会发生光化学Z/E异构化。然而，通过红外和核磁共振对构象异构体的研究在常规操作过程中不受影响，无需进行光保护。
