✦ Synopsis

Complete 1H and 13C NMR chemical shift assignments were made for taraxerene from HMQC and HMBC spectra. Methyl proton shifts were assigned for 11 other taraxerenes. Molecular mechanics calculations and NMR evidence supported the p-bromobenzyl acetylaleuritolate x-ray conformation for taraxerenes in solution.

The proton and carbon spectra for the fertility-regulating agent, pseudolaric acid B (l), have been assigned using a combination of one-and two-dimensional NMR spectroscopic techniques. NOE difference measurements revealed an unexpected conformation of the molecule, which could only be explained by

## Abstract The solution conformation of β‐casein phosphopeptide (CPP) was studied by ^1^H NMR spectroscopy. As a prerequisite to the conformational analysis the spectral assignment was carried out for CPP in the Ca^2+^‐free and ‐bound states by the use of two‐dimensional NMR spectroscopy. The assi
