Dissociative multiphoton ionization of NO2 studied by time-resolved imaging

“…The pump pulse, centered at ϳ400 nm, excites jet-cooled molecules initially in the lowest vibrational and rotational levels of the X 2 A 1 state to zero-order rovibrational levels of the à 2 B 2 state. The population in the à 2 B 2 state can be probed by two-photon ionization through a number of Rydberg states ͓1 2 ⌺ u ϩ (3p) is illustrated͔ converging to the X 1 ⌺ g ϩ state of NO 2 ϩ or as in the experiments of Abel et al 36 by monitoring the fluorescence from these intermediate states. In our experiments, we detect NO ϩ , NO 2…”

Absolute Rate Constants for Collisional Vibrational Relaxation in Dense Vibrational Regions of S1 p-Difluorobenzene

“…A method to do so has not been devised, and in the absence of experimental data, Lennard-Jones rate constants are generally assumed for the modeling. [12][13][14][15][16][17][18][19][20][21][22][23][24][25] It is useful to learn experimentally about the validity of the Lennard-Jones assumption. Our previous state-to-field VET measurements may help one do this since they involve processes analogous to those of the activation/deactivation problem.…”

“…None, however, has ever been measured for these regions where the vibrational state density is so high that a vibrational quasi-continuum is present. A method to do so has not been devised, and in the absence of experimental data, Lennard-Jones rate constants are generally assumed for the modeling. − …”

State-to-state rate constants for collision induced energy transfer of electronically excited NH2 with NH3

“…where L is N or K as suggested by Brunner and Pritchard 35 or applied by Abel et al 39 Fits with about the same standard deviation are also obtained with the so-called AON ͑a over n͒ fitting law developed by Whitaker and Brechignac. 37,40,41 In this case, stateto-state rate constants are obtained from Eq.…”
