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. |
