Abstract

Two sets of experiments dealing with the upper excited states of DNA are presented here. In one investigation, one-photon excitation of DNA with low intensity UV laser radiation (199.8, 217.8, and 239.5 nm) is exploited to assess damage done upon excitation to singlet states higher than the first excited singlet state. In another, the sequential excitation of DNA with 266 nm laser radiation and 532 nm photons was explored using ps laser radiation.
