AbstractThe photodissociation dynamics of ICH2Cl -> CH2Cl + I-star/I at 304 and 277 nm has been investigated with our mini-TOF photofragment translational spectrometer with a weak acceleration field of <1 V cm(-1). Many peaks are resolved or partially resolved in the TOF spectra and the photofragment translational spectra (PTS) of both the I-star(P-2(1/2)) channel and the I(P-2(3/2)) channel. These resolved peaks are assigned to the C-Cl stretch vibrational states of the CH2Cl fragment. The rotational energy E-R of the CH2Cl fragment is highly excited due to its asymmetric structure. The value of E-R/E-T is measured to be about 0.71. In the I-star channel, the partitioning of the available energy E-avl into the translational energy E-T, the rotational energy E-R, and the vibrational energy E-V for each resolved vibrational state has been calculated.
