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 کاملAb initio vibrational predissociation dynamics of He-I2(B) complex.
Three-dimensional quantum mechanical calculations on the vibrational predissociation dynamics of HeI2 B state complex are performed using a potential energy surface accurately fitted to unrestricted open-shell coupled cluster ab initio data, further enabling extrapolation for large I2 bond lengths. A Lanczos iterative method with an optimized complex absorbing potential is used to determine ene...
متن کاملDynamics of linear and T-shaped Ar–I2 dissociation upon B—X optical excitation: A dispersed fluorescence study of the linear isomer
We report the dispersed fluorescence spectra of the linear and the previously well-studied T-shaped isomers of Ar–I2 following B←X optical excitation for vpump516– 26, below the I2 dissociation limit. The linear isomer has a continuum excitation spectrum. For excitation at the highest pumping energy (vpump526), the product vibrational state distribution is nearly identical to that observed 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 کاملDirect observation of the picosecond dynamics of 1 2 - Ar fragmentation
The fragmentation of van der Waals (vdW) complexes offers an opportunity for studying the half-collision dynamics in well-defined systems. In previous work from this laboratory, we have studied, 1 in real time, the dynamics of the "hair' and the "full" collision, but we had no results on the diatom-rare gas small vdW complexes. Iodine with rare gases I2-M (M =He, Ne, and Ar) are of particular i...
