Competition between adiabatic and nonadiabatic fragmentation pathways in the unimolecular decay of the ArI2(B) van der Waals complex.
The competition between vibrational and electronic predissociations of the ArI2(B) van der Waals complex has been studied using several dynamical computational methods: exact quantum wave-packet propagation, time-dependent golden rule, and quasiclassical trajectory with quantum jumps model. Five electronic states are considered using recent three-dimensional coupled surfaces obtained with a per...
متن کاملA theoretical study on electronic predissociation in the NeBr2 van der Waals molecule
0301-0104/$ see front matter 2011 Elsevier B.V. A doi:10.1016/j.chemphys.2011.09.015 ⇑ Corresponding author. E-mail address: [email protected] (K.C. Janda). We present the first comprehensive ab initio study of the Ne–Br2 potential energy surfaces and the nonadiabatic couplings between the valence excited electronic states. These ab initio results are used to obtain 3-D approximate potentials for...
متن کاملNeCl2 and ArCl2: transition from direct vibrational predissociation to intramolecular vibrational relaxation and electronic nonadiabatic effects.
Pump-probe results are reported for NeCl(2) excited to the Cl(2) B state, undergoing vibrational predissociation, and then probed via E <-- B transitions. Intensities, lifetimes and product vibrational branching ratios are reported for 16 < or = v' < or = 19 Cl(2) stretching quanta. The intensity of the signal rapidly decreases above v' = 17. Detailed wave packet calculations of the vibrational...
متن کاملCommunications: A model study on the electronic predissociation of the NeBr(2) van der Waals complex.
Recently, the predissociation lifetimes of the NeBr(2)(B) complex for different initial vibrational excitation (10<or=v(')<or=20) have been measured using time-resolved optical pump-probe spectroscopy [Taylor et al., J. Chem. Phys., 132, 104309 (2010)]. In the vibrational interval studied, the vibrational predissociation (VP) proceeds by the transfer of a single vibrational quantum and the life...
متن کاملReal - time dynamics of clusters . I . 1 , X , , ( n = 1 )
For I, Ne, the values of r = k ’ (v],z$) decrease nonlinearly from 2 16 ps for v] = 13 to 53 ps for vi = 23. For 1,Ar (B,vj), which undergo electronic and vibrational predissociation, the risetime of the nascent I, is found to be 70 ps when 0; = 18 and 77 ps when v] = 21. A number of theoretical models for vibrational predissociation (the energy-gap law, the momentum-gap law, quantum and classi...
