Exploring the Mechanism of IR–UV Double‐Resonance for Quantitative Spectroscopy of Protonated Polypeptides and Proteins1. Issue 23 (25th April 2013) - Nagornova, Natalia S.
Abstract Spectroscopic fingerprint: Infrared–ultraviolet double resonance photodissociation is used for conformational assignment of the electronic spectra of a cold protonated decapeptide (see picture). A mechanism of the IR–UV depletion spectroscopy is proposed and a procedure of using it for measurements of absolute absorption cross‐sections of vibrational transitions is elaborated.
