Table 1.
Time constants and percent amplitudes (in parentheses) from global fits to transient signals of d(GC)9·d(GC)9 in H2O and D2O.a,b Amplitudes do not sum to one hundred percent due to a small amount of residual photobleaching.

a
Stated uncertainties are twice the standard error.
b
Parameters with identical values and uncertainties were globally linked during fitting.
