AbstractUltrafast vibrational relaxation dynamics of LDS698 dye: molecule in solution are theoretically studied on the basis of the perturbative density operator method and the transient linear susceptibility theory. Femtosecond time-resolved profile on stimulated emission pumping fluorescence depletion is simulated for the system with the single vibrational mode. The vibrational transition rate constant gamma(1-->0) is 4.5 ps(-1), the two constants C-1 and k relating to the solvation are 1.0 and 0.08 ps(-1) respectively. It is 2.4 for the Huang-Rhy factor S between the first excited S-1 state and the ground S-0 state. The SEP signal reveals that the fast;ind tilt: slow decay components reflect the vibrational relaxation and the excited state solvation of the molecule. respectively.
