✦ Synopsis

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 (C1(32P,,2)). The following quenching rate constants have been obtained: (1.8 *0.4)x lo-", (1.7*0.4)~10-'~, (7.4+2.6)x10-'3 and ~1O-l~ cm3/s for CF2C12, 02, Cl, and Ar respectively. The mixing rate constant of hyperfine structure levels for the 'F',,, state has been estimated for collisions with molecular oxygen, (4.0 +0.8)x lo-l2 cm3/s.
