Abstract

Proton and12C NMR study of molecules related to retinal has been carried out. The characteristic differences in spectral behaviour among 7-trans and 7-cis isomers have been established which would be useful in determining the structure of new isomers and identifying components in a mixture. Through coupling constant measurements and DNMR study it is clearly established that 7-cis isomers of β-ionyl derivatives and in turn 7-cis isomers of retinyl derivatives prefer a non-planar arrangement and this non-planarity brings about resonance destabilisation.
