Saturation by Optical Pumping in CW LIF Spectra of Cal

Laser-Induced Fluorescence Studies of Excited Sr Reactions. 1. Sr(3P1) + HF

“…This is in contrast to pulsed LIF, where the signal is proportional to the density of molecules. 24,25 Therefore, the population distributions as derived from the spectra directly reflect the relative state-specific reaction cross sections.…”

Quasi-classical trajectory study of the reaction dynamics of Ca(1S0,3P) atoms with CHCl3

“…The relatively high fraction of the available energy disposed into vibration of the diatomic product was indicative of an early energy release. The variation of the disposal into vibrational energy of the formed diatom among the various systems was attributed to a variation of the harpooning radius and its magnitude relative to the interatomic distance of the diatomic product [6,7]. Using Laser-induced chemiluminescence in a beam-gas apparatus, Yang et al [21] have carried out total collision cross-sections and chemiluminescent cross-sections for the Ca( 1 P) + CH 3 Cl, CH 2 Cl 2 , CHCl 3 , and CCl 4 .…”

“…In the past several decades, the detailed reaction dynamics between alkaline earth metal atoms and halogenated methanes has been attracting much extensive attention both theoretically and experimentally [1][2][3][4][5][6][7][8][9]. Laser induced fluorescence (LIF) is the most popular method to study alkaline earth monohalides, and a pulsed laser are also used in most cases [1][2][3][4][5][6][7][8][9][10].…”

“…Specific reactions have been investigated experimentally under single collision conditions for the following reactions, such as Sr + XF (X is alkyl) [1][2][3][4][5][6][7][11][12][13][14][15], Ba + XI (X is alkyl) [10,16,17], Ca/Ba + CH 3 X (X = Br, I) [7,[16][17][18][19], Ba + HX [20], etc. The reaction Ca + CH 3 X (X = Br, I) was investigated by Keijzer et al with continuous-wave LIF spectra [6,7]. They showed that the LIF spectra of CaBr formed in the reactions of Ca with CH 3 Br could be interpreted as a sum of a thermal and a nonthermal spectrum.…”
