The excited-state lifetimes in a G x C DNA duplex are nearly independent of helix conformation and base-pairing motif.
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).
