Abstract

Picosecond photodynamics of triphenylmethyl cation dyes are examined in the visible spectral region with time and wavelength resolved spectroscopy. Computer modeling of the data is employed to determine recovery times for ground state absorption. Previous work is reviewed and compared to the current results. It is proposed that dielectric relaxation is the controlling step in the return of ground state absorption, rather than viscosity as proposed by previous authors. Data is presented from studies in the field of dielectric relaxation to support this contention.
