The temperature dependence of the collisional removal of O 2 in the v=1 and 2 vibrational levels of the b 1 Σg+ state by O 2, N 2, and CO 2 has been investigated over the K temperature by: Get this from a library! Temperature dependence of the collisional removal of O2(A(sup 3)Sigma(sup +)(sub u), upsilon=9) with O2 and N2. [Eunsook S Hwang; Richard A Copeland; United States.

Abstract  Total removal rate constants of OH(υ = 9) by O atoms, O 2, O 3, N 2, and CO 2 were measured at room temperature. Ozone photodissociation at nm in a mixture conta.
In contrast to O2(b1Σg+,υ=0), collisional removal of O2(b1Σg+,υ=1) by O 2 is very rapid; the two most recent measurements of the room-temperature rate coefficient for this process produced values of ( ± ) × 10 −11 cm 3 s −1  and ( ± ) × 10 −11 cm 3 s −1 .Cited by: The rate coefficients for the collisional deactivation of Tl(62P32) by several gases has been determined at °K. This data is compared with that pre Cited by: Production of two metastable O2 species, O2(a1Δg, υ = 0) and O2(b1Σg+, υ = 0), from collisional removal of O2(A3Σu+) by O2 and N2 is investigated at a temperature of K.

(a) Simulated nascent O 2 (b‐X) 0‐0 and 1‐1 emissions with the collisional removal effects removed, as described in the text, demonstrating that almost all observed b(0) originates with b(1).Cited by: 4.
The collisional deactivation of O(1S) by CO2, O2, N2, and Ar has been investigated as a function of temperature in the range from to °K. O(1S) was produced in a pulsed mode by vacuum ultraviolet flash photolysis of CO2. The decay of O(1S) was observed by the Å emission as a function of time after the production pulse. Deactivation rate constants were derived from the dependence Cited by: The temperature dependence of the collisional removal of O2 in the v = 1 and 2 vibrational levels of the b 1Σg+ state by O2, N2, and CO2 has been investigated over the – K temperature range. The temperature dependence of the collisional quenching of OH (A 2 Σ +, v′ = 0) has been studied in a discharge-flow system between and K for the collision gases N 2, O 2 and CO ing cross-sections were observed to increase with decreasing temperature, consistent with attractive forces dominating the collision process. The temperature dependence of the calculated rate constants for the quenching of O 2 (b 1 Σ g +, v = 1–3) by CO 2 (0, 0, 0) is in good agreement with experimental removal rates of,,.Cited by: 9.
