1. 13C NMR Spectroscopic Studies of Intra- and Intermolecular Interactions of Amino Acid Derivatives and Peptide Derivatives in Solutions

Author

Yoshikazu Hiraga, Saori Chaki, Yuri Uyama, Ryosuke Hoshide, Takumi Karaki, Daisuke Nagata, Kanji Yoshimoto, and Satomi Niwayama

Subjects
13C NMR spectroscopy, IR spectroscopy, carbonyl group, amino acids, peptides, solvent polarity, Organic chemistry, QD241-441
Abstract

13C NMR spectroscopic investigations were conducted for various amino acid derivatives and peptides. It was observed that 13C NMR chemical shifts of the carbonyl carbons are correlated with the solvent polarities, but the extent depends on the structures. The size of the functional groups and inter- and intra-molecular hydrogen bonding appear to be the major contributors for this tendency.
