By using a pump-probe technique, the nascent rotational and vibrational state distributions of CsH are obtained in the Cs(6 2 𝐷,7 2 𝐷) plus H2 reaction. The nascent CsH molecules are found to populate the lowest two vibrational (𝑣 ′′ = 0 and 1) levels of the ground electronic state. By comparing the spectral intensities of the CsH action spectra with those of pertinent Cs atomic fluorescence excitation spectra, the relative reactivity with H2 is in an order of 6 2 𝐷 3/2 > 6 2 𝐷 5/2 > 7 2 𝐷 3/2 > 7 2 𝐷 5/2 . The rotational temperatures are found to be slightly below the cell temperature. The relative fractions (⟨𝑓𝑉 ⟩, ⟨𝑓𝑅⟩, ⟨𝑓𝑇 ⟩) of average energy disposal are derived as (0.2,0.12,0.68), (0.2,0.12,0.68), (0.07,0.04,0.89) and (0.07,0.04,0.89) for the 6 2 𝐷 3/2 , 6 2 𝐷 5/2 , 7 2 𝐷 3/2 and 7 2 𝐷 5/2 , respectively. The major available energy is released as translation. These results support that the reaction mechanism of Cs(6 2 𝐷,7 2 𝐷) plus H2 is primarily a collinear abstraction and not an insertion.

A K-N2 mixture is irradiated in a glass fluorescence cell with pulses of 710 nm radiation from an OPO laser, populated K2 ( 1 Λ𝑔) state by two-photon absorption. The cross section for 1 Λ𝑔 → 3 Λ𝑔 transfer in K2 is determined using molecular fluorescence spectrometry. The cell temperature is kept constant at 553 K. The N2 pressure is varied between 40 Pa and 400 Pa. The effects of K2-K collisions could not be neglected. These effects are subtracted out by using the results of the pure K experiment. The cross sections are (3.8 ± 1.5) × 10 −15 cm 2 for K2 ( 1 Λ𝑔) + N2 → K2( 3 Λ𝑔) + N2 and (8.9 ± 3.5) × 10 −15 cm 2 for K2 ( 3 Λ𝑔) collisions with N2.
