Infrared hole burning of the amino group in amino acid and peptide salts

Article Abstract:

Infrared spectroscopy is employed for examining the monodeuterated derivatives of the salts of tyrosine, valine, glycylglycine and glycylglycylglycine, thus facilitating the study of the infrared hole burning of the amino group in amino acid and peptide salts. Results indicate that the irradiating of the N-D stretch bands of a variety of amino acid salts and simple peptide salts changes the conformation of the NH2D(super +) groups, thus changing the conformation and giving rise to the holes in the irradiated stretch bend.
