a
The degree of correlation (C) is approximated by fitting equation 4 to reproduce the decay rate estimated by the fit as discussed in the text. The numbers in parentheses represent the correlation needed to reproduce the low and high range for the decay rate.
b
Errors reported are standard deviations for experimental fits.
c
We assign ω2 from feature C to a non-resonant toluene solvent mode.
