Assignment of 1H and 13C NMR Spectra of Retinoic Acid Ester Isomers Observed in the Long-Wavelength UV-Induced Photostationary State

Article abstract of DOI:10.1002/mrc.1260270722

1H and 13C chemical shift assignments, obtained with the aid of two-dimensional hetenuclear shift correlation and double-quantum coherence 13C-INADEQUATE experiments, are reported for four retinoic acid ester isomers observed at the photostationary state.Also detailed are 1H assignments for three additional isomers obtained in insufficient amounts for 13C measurements.KEY WORDS - Retionic acid esters Isomer identification 1H-13C correlation spectra 13C-INADEQUATE experiment
