The Excited‐State Lifetimes in a G⋅C DNA Duplex are Nearly Independent of Helix Conformation and Base‐Pairing Motif

Abstract
DNA photophysics: Femtosecond transient absorption experiments reveal that excited states produced by UV light in a duplex DNA oligonucleotide decay at essentially the same rate in B and Z helix conformers (see figure). magnified image
