Secondary structure of peptides. 17—Cis/trans isomerism of solid proline‐containing oligopeptides as revealed by 13C NMR CP/MAS spectroscopy
TL;DR: In this paper, the 75.4 MHz 13C NMR CP/MAS spectra of five classes of solid proline peptides were measured: cyclodipeptides, unprotected dipeptides and N-tert-butoxycarbonyl- (Boc) derivatives.

Macrocycles, 22 Synthesis and characterization of cyclic poly(bisphenol A carbonate)s by interfacial polycondensation of bisphenol-A with diphosgene
TL;DR: In this paper, the phosgenation of bisphenol A with diphosgene in the CH 2 CI 2 /NAaOH system was studied using the pseudo-high-dilution method either with triethylamine, with triethylbenzyl ammonium chloride (TEBA-C1), or with tetraphenylphosphonium chloride as catalyst.

15N NMR spectroscopy acids: 7—solvent effects on α‐and ω‐amino
TL;DR: In this paper, the natural abundance 15N NMR spectra of several α-and ω-amino acids were measured in various protic solvents, and the upfield shift in the case of α-aminos acids was observed.
