Journal ArticleDOI
Carbon 13 nuclear magnetic resonance of peptides in the amino-terminal sequence of sperm whale myoglobin.
TL;DR: Signals assignments were made by comparison of the peptides with each other and with the free amino acids, by the pH dependence of the chemical shifts, and by modification of the degree of proton decoupling in certain cases.

TL;DR: The carbon shifts of the Iboga-type alkaloids catharanthine, voacangine, coronaridine, ibogaine, dihydrocatharanthines and epiibogamine were recorded and correlated with the conformation of the natural bases.
