H-bonding effects on the IR and NMR spectra of N-tosyl-amino acid 2,6-bishydroxylmethyl pyridine monoesters.
H-bonding in the title monoesters affects the most utilized types of spectrometries-infrared (IR) and nuclear magnetic resonance (NMR). The shifts of the three kinds of A-H stretching bands to lower wavenumbers in the vibrational spectra, and the 1H chemical shifts, which are to the low field, are observed and reasonably explained in this paper.
