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.
