Ultrafast IR spectroscopy of the short-lived transients formed by UV excitation of cytosine derivatives

Chem Commun (Camb). 2007 Jun 7:(21):2130-2. doi: 10.1039/b703344c. Epub 2007 May 3.

Abstract

A strong infrared band at 1574 cm(-1) is observed following 267 nm excitation of 2'-deoxycytidine (tau = 37 +/- 4 ps) or 2'-deoxycytidine 5'-monophosphate (tau = 33 +/- 4 ps); this band is provisionally attributed to an 1n(N)pi* state and is absent for cytosine.
