Ab 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 کاملCollisional relaxation of highly excited vibrational levels of I2(X)
The relaxation dynamics of vibrationally excited levels of I2(X) are of relevance to the chemical oxygen iodine laser. We have investigated relaxation of 12(vM>20) by pulsed laser techniques. Individual ro-vibrational levels were populated by stimulated emission pumping. Collisionally populated levels were monitored via laser excitation of the D-X transition. Preliminary rate constants for vibr...
متن کاملUltrafast vibrational relaxation of diatomic chalcogen hydrides in alkali halides
The energy relaxation times of the fundamental stretching modes in the electronic ground state of OH, OD, SH, and TeH in a variety of alkali halides are measured by incoherent laser saturation and found to vary from 0.3 to 3 ns at 1.7 K. These vibrational lifetimes are between 4 and 8 orders of magnitude smaller than those of other heteronuclear diatomics diluted in crystals, including the ioni...
متن کاملFranck-Condon effects in collision-induced electronic energy transfer: I2(E; v = 1,2) + He, Ar.
Collisions of I2 in the E electronic state with rare gas atoms result in electronic energy transfer to the D, beta, and D' ion-pair electronic states. Rate constants for each of these channels have been measured when I2 is initially prepared in the J = 55, nu = 1 and 2 levels in the E state. The rate constants and effective hard sphere collision cross sections confirm the trends observed when n...
متن کاملDissociation of Diatomic Molecule by Energy-Feedback Control
New method for dissociation of diatomic molecule based on nonperiodic excitation generated by energy-feedback control mechanism is proposed. The energyfeedback control uses frequency-energy (FE) relation of the natural oscillations to fulfill the resonance conditions at any time of excitation. Efficiency of the proposed method is demonstrated by the problem of dissociation of hydrogen fluoride ...
