Transient NEXAFS Spectroscopy at the Oxygen Edge: Pinning Down ππ*/nπ* Internal Conversion

Not Accessible

Your library or personal account may give you access

Abstract

We present results from time-resolved NEXAFS spectroscopy at the oxygen edge, which show an extremely high sensitivity on ππ* to nπ* internal conversion. Application to thymine clarifies the current picture of its photoprotection mechanism.
