Generation of Kr( 3P 0) atoms in a flow reactor: Reactions with CO, N 2, NF 3, and F 2
Abstract
Optical pumping of atoms from the Kr(5s, 3P 2) state to the Kr(5p', 2p 3) state with a cw dye laser followed by subsequent radiative decay has been used to convert ≈23% of the concentration in the Kr( 3P 2) state to the Kr( 3P 0) state in a flow reactor. The CO (b 3Σ +, ν' = 0, 1-a 3Π) emission can be used as a diagnostic test for Kr( 3P 0) in the presence of Kr( 3P 2). Quenching of Kr( 3P 0) by N 2 apparently leads to dissociation. The degree of conservation of the Kr + ( 2P 1/2) ion-core configuration in the reaction of Kr( 3P 0 with NF 3 and F 2 was monitored by observing the propensity for KrF(D) formation.
