dc.description.abstractTo provide physicists, Nicholas L. Evans and Susanne Ullrich, at the University of Georgia (UGA) with the statistical support to determine the decay lifetimes of the photo-excited DNA nucleobase Adenine, which is one of the four basic DNA nucleobases, we developed and applied a set of statistical analysis methods, including background signal analysis, inversevariance-weighted Gaussian fitting, Gaussian-weighted summation, and non-linear regressions with the Single- model in the long-lived and short-lived channels of TRPES experiments of Adenine, through applying SAS procedures and C++ computer programming. For one TRPES data set, we obtained the decay lifetimes 1 = 884 fs for the long-lived channel and 2 = 67 fs for the the short-lived channel, both of which are in a good agreement with experimental results of 1 = (880 ± 50) fs and 2 = (70 ± 30) fs [1]. With another TRPES data set, we validated our methods, obtaining estimates of 1 = 917 fs and 2 = 91 fs.
