Ultraviolet-resonance femtosecond stimulated raman study of the initial events in photoreceptor chromophore

Abstract

Newly-developed ultraviolet-resonance femtosecond stimulated-Raman spectroscopy was utilized to study the initial structural evolution of photoactive yellow protein chromophore in solution. The obtained spectra changed drastically within 1 ps, demonstrating rapid in-plane deformations of the chromophore. © Owned by the authors, published by EDP Sciences, 2013.
