Theoretical study of vibrational relaxation and internal conversion dynamics of chlorophyll-a in ethyl acetate solvent in femtosecond laser fields

Seen from the caricature, the faster process of the FDS reflects the vibrational relaxation. The slower process describes the excited solvation effect of the Chl-a molecule in ethyl acetate solvent. The calculated FDS of Chl-a agrees well with the experimental result of Shi et al. [Shi et al., Chem. Phys. Lett. 410 (2005) 260].
