Transient absorption profiles of pure diethylene glycol and ribothymidine solutions under ambient conditions. Spectra (a, c) and kinetics (b, d) for neat DEG and 0.3 M ribothymidine (rT) solutions, respectively. The region at 780 nm is filtered out. The duration of the electron pulse is ~7 ps. The dose per electron pulse is 25.3 Gy
