## Abstract A new class of retinoic acids was synthesized containing a 9,10‐rigid bond. ^1^H and ^13^C NMR spectra were assigned for eight new compounds (all‐__E__, 13__Z__) containing a carboxylic acid or tertiobutylester polar end group. Assignments were based on the combination of one‐ and two‐

✦ Synopsis
H and 13C chemical shift assignments, obtained with the aid of two-dimensional heteronuclear shift correlation and doublequantum coherence ' 3C-INADEQUATE experiments, are reported for four retinoic acid ester isomers observed at the photostationary state. Also detailed are ' H assignments for three additional isomers obtained in insufficient amounts for 13C measurements.

## Abstract The assignments of the long‐range ^13^C, ^1^H coupling constants in the ^13^C NMR spectra of the base moieties of several purine and pyrimidine nucleosides and their analogues were established by the application of long‐range selective ^1^H decoupling with low‐power ^1^H irradiation. Th
