| 英文摘要 | The 304 nm photodissociation of the C-H symmetric stretch excited CH3I [v (1) = 1, v (2) = 0] (v (1) denotes the C-H symmetric stretch mode, and v (2) denotes the umbrella mode) is studied with our simple photofragment translational spectrometer. An IR laser is used to excite the ground state CH3I [0, 0] to the C-H symmetric stretch excited CH3I [1, 0]. With IR laser OFF and ON, the fractions of photofragments CH3 (nu (1), nu (2)) from the 304 nm photodissociation of CH3I [1, 0] have been determined through the photofragment translational spectra (PTS) from measuring I and I* and also through the PTS from measuring CH3 (0, 0) (1, 0) (0, 1) and (1, 1). The experimental results show that the C-H symmetric stretch vibration (v (1) = 1) in parent molecules is about 66% retained in the photofragments in the I channel, but only 24% in the I* channel. The populations of photofragments CH3 (0, 2) and (0, 3) are higher than CH3 (0, 0) and (0, 1), showing strong inverted population both in I and I* channels. |
