Oxalyl chloride photofragment imaging: One photon - four fragments
- Lawrence Berkeley National Lab., CA (United States)
Recently we have built an crossed molecular beams ion imaging system to study reactive scattering and photodissociation dynamics. The ion imaging machine has been designed to incorporate tunable vaccuum ultraviolet radiation generated by the Advanced Light Source to carry out soft ionization of product species. Here we present first results of the photodissociation dynamics of oxalyl chloride (CLCO)2. In this case photolysis and probe light were generated using Nd-YAG pumped dye lasers. With the absorption of one photon around 230 nm, the molecule breaks apart into four fragments (Cl + CO + CO + CL). The velocity and angular distributions of these fragments are studied using resonantly enhanced mutiphoton ionization and imaging techniques. Photofragment translational energy and angular distributions are presented for ground state and spin-orbit excited Cl atoms as well as for individual rotational levels of the CO product. These distributions suggest a simple model for the dissociation dynamics.
