Abstract
Preresonant Raman spectra of Gly-Pro, Pro-Gly, and N-acetylproline methylamide with excitations between 240 and 200 nm are presented. It is shown that, with excitation near 230 nm, vibrations of the X-Pro bond are preferentially enhanced by approximately a factor of 30 relative to vibrations of the normal peptide bond.
