摘要
In the presence of linearly varying frequency chirped laser pulses, the photodissociation dynamics of D-2(+) is studied theoretically after ionization of D-2. As a completion of our recent work [A. Csehi et al., J. Chem. Phys. 143, 014305 (2015)], a comprehensive dependence on the pulse duration and delay time is presented in terms of total dissociation probabilities. Our numerical analysis carried out in the recently introduced light-induced conical intersection (LICI) framework clearly shows the effects of the changing position of the LICI which is induced by the frequency modulation of the chirped laser pulses. This impact is presented for positively, negatively, and zero chirped short pulses. (C) 2016 AIP Publishing LLC.
