Laser induced fluorescence in CO2, (CO2 + 14N2), (CO2 + 15N2) and (CO2 + He)

Chemical Physics Letters, 1972
Abstract Vibrational deactivation in CO 2 ( v 3 mode) is studied extensively in CO 2 , CO 2 + 14 N 2 , CO 2 + 15 N 2 and CO 2 + H by use of the laser induced fluorescence technique covering the entire range of concentration (0–100 per cent) in the temperature range 300–500°K.

Dynamics of CO2/CO2 Laser

Nonlinear Dynamics in Optical Systems, 1990
Numerically we study the five-dimensional dynamical system which describes a laser with saturable absorber. The bifurcation diagrams are plotted for the parameters corresponding to real CO2-laser with CO2 as the saturable absorber. The influence of external noise is investigated.

Intermolecular Potentials for the Systems CO2–CO2 and CO2–N2O

The Journal of Chemical Physics, 1952
Experimental values of self-diffusion and mutual diffusion coefficients, in the range −78° to 90°C, have been used to determine the intermolecular potentials for the systems CO2–CO2 and CO2–N2O. It has been assumed that a spherically symmetric potential of the form V (r)=4ε[(σ/r)12—(σ/r)6] may be used and that the dynamics of the diffusion process are ...

Reactions of CO2+ and CO2 · CO2 with ethylene. Heat of formation of CO2 · CO3+

International Journal of Mass Spectrometry and Ion Physics, 1980
Abstract Rate coefficients and product distributions for the reactions of CO2+ and CO2 · CO2+ with C2H4 were determined in a drift chamber filled with CO2 at 0.3 torr. The rate coefficient are k3 = 0.9 × 10−9 cm3 s−1 for CO2+ and k5 = 1.0 × 10−9 cm3 s−1 for CO2 · CO2+.
