Аннотация:The dynamics of the isomerization of spiropyran was simulated based on the two-well model potential. The possibility of effective control over the transition using phase-modulated (chirp-modulated) laser femtosecond pulses was studied. The probability of transitions to the A and B forms from the excited S1state was evaluated at 1 : 5; i.e., the efficiency of the transition reached 80%. It is phase the modulation of vibrationalpackets (purely quantum effect) that makes it possible to effectively control the behavior of the system, but oneparameter quartic modulation seemed not sufficient for total control.
