A re-examination of the line shape of the electronic spectra of complex molecules in solution: log-normal function versus gaussian

Abstract

The log-normal function and the Gauss function have been tested for the description of highly structured UV/Vis spectra of complex molecules in solution. The Gauss function was shown to give the better fit for these spectra and is also useful for fluorescence spectra. These results were further supported by the application of the Ross function.
