✦ Synopsis

Complete ' 3C and ' H spectral assignments for two series of liquid crystals in CDCI, solution were made. The 4-(trans-4- alkylcyclohexyl)benzonitriles had propylto pentyl-substituted alkyl chains, whereas the 4-(trans-4-alkenylcyclohexyl) benzonitriles had varying positions of the alkenyl bond. "C and 'H chemical shifts and 13C-' H scalar coupling constants are reported.

## Abstract Complete ^13^C and ^1^H NMR spectral assignments for a series of derivatives of the naturally occurring C‐ring aromatic diterpene resin acid dehydroabietic acid have been made. The use of a combination of 1D and 2D NMR techniques allowed mostly unambiguous assignments of all ^13^C reson
