The 500 MHz proton spectra of monomeric bacteriochlorophyll a and chlorophyll a were recorded and assigned. The proton chemical shifts and proton-proton coupling constants were all determined except for the P-5 to P-15 phytyl side-chain protons. The conformational structures of the reduced rings an

## Abstract The complete ^1^H and ^13^C NMR spectra of the mycotoxin zearalenone are described. An analysis of all the vicinal proton–proton coupling constants, together with molecular modelling results, leads to a three‐dimensional structure very similar to those observed x‐ray crystallographicall

## Abstract Carbon and proton NMR spectra of 3‐hydroxypyridine and its O‐methyl and N‐methyl derivatives have been analysed, and are compared with the spectra of the corresponding 2‐ and 4‐substituted pyridines. It is shown, that contrary to quantum chemical predictions and in agreement with chemic
