Can Internal Conversion BE Controlled by Mode-Specific Vibrational Excitation in Polyatomic Molecules Conference Paper uri icon

abstract

  • Nonadiabatic processes, dominated by dynamic passage of reactive fluxes through conical intersections (CIs) are considered to be appealing means for manipulating reaction paths. One approach that is considered to be effective in controlling the course of dissociation processes is the selective excitation of vibrational modes containing a considerable component of motion. Here, we have chosen to study the predissociation of the model test molecule, methylamine and its deuterated isotopologues, excited to well-characterized quantum states on the first excited electronic state, S_ {1}, by following the NH (D) bond fission dynamics through sensitive H (D) photofragment probing. The branching ratios between slow and fast H (D) photofragments, the internal energies of their counter radical photofragments and the anisotropy parameters for fast H photofragments, confirm …
