(a) Population of the ground state of the closed ring isomer under UV pulse laser irradiation (cyclization). (b) Population of the first excited state of the closed ring isomer according to the temperature under vis pulse laser irradiation (cycloreversion). (c) Temperature dependency of time constants of calculated population under vis pulse laser irradiation. The constants of our model and Ishibashi et al.23 are normalized by each value at 343 K.
