摘要：
The role of another excited pyrene molecule in the vicinity of an excited pyrene molecule undergoing electron transfer (ET) process with a N,N,-dimethylaniline molecule has been explored in non-polar and polar solvent where specifically solvent mediated nature of ET is prominent. Analytic expression has been derived for the dependence of ET kinetics on pyrene concentration in the experimental conditions normally encountered in sub-nanosecond time correlated single photon counting (TCSPC) apparatus which is mostly used. The life time data has been explained on the basis of present day understanding. (C) 2019 Elsevier B.V. All rights reserved.
