Theoretical analysis of internal conversion pathways and vibrational relaxation process of chlorophyll-a in ethyl ether solvent

Seen from the caricature, the calculated FDSs indicate that the sequential IC process is a main pathway for the population transfer from the S3 state to the S1 state. The calculated FDSs of Chl-a in ethyl ether solvent agree well with the experimental results of Shi et al.
