Abstract

Time-resolved LMR combined with fast magnetic field jump has been employed to study collisional quenching of the upper state of a chlorine atom fine structure (Cl(32P 1 2)). The following quenching rate constants have been obtained: (1.8±0.4) × 10-10 (1.7±0.4)×10-13, (7.4±2.6)×10-13 and ≤ s10-14 cm3/s for CF2Cl2, O2, Cl2 and Ar respectively. The mixing rate constant of hyperfine structure levels for the 2P 1 2 state has been estimated for collisions with molecular oxygen, (4.0±0.8)×10-12cm3/s. All the data correspond to T = 298±5 K.
