摘要

During the last year we: (1) measured the rotational and vibrational distribution of the S sub 2 produce of the spin conserving reaction: S( exp 1 D) + OCS implies S sub 2 (a exp 1 delta ) + CO; (2) developed a two photon laser induced fluorescence method for the time resolved detection of carbon atoms in both their ground exp 3 P and metastable exp 1 D states; (3) showed that the reaction F + HI implies HF + I produces I atoms only in the exp 2 P/sub 3/2/ state; (4) observed for the first time in the gas phase the Walden inversion: F + CH sub 3 I implies CH sub 3 F + I, with both J=3/2 and J=1/2 atoms being produced in a 2/1 ratio; (5) showed by laser induced fluorescence that the IF product of the reaction: F + RI implies R + IF (R = CH sub 3 ,C(CH sub 3 ) sub 3 ,CF sub 3 ) is vibrationally and rotationally cold.
