Study of the Vibrational Structure of Uridine in Aqueous Solution by Phase-mismatched CARS
CARS spectra of Uridine in aqueous solution are examined in the region of 900~1500 cm-1. The nonresonant background has been remarkably suppressed by using a phase mismatching method. The ring skeletal stretching modes of base, C-H bending modes and N-H bending mode can be assigned unambiguously, and the very weak vibrational modes of ribose are also oberved. The experimental conditions of the phase mismatching technique are discussed with a numerical calculation. We conclude that background-eliminated CARS measurement is a powerful tool for studying the structures of nucleic acids.
