Abstract
We report on the use of '2D' time-velocity correlations to study in re al time the dynamics of reactions with multiple channels. By resolving the kinetic energy on the femtosecond time scale we are able to direc tly identify the direct-mode and complex-mode dissociation pathways of iodobenzene. The coherent wave packet dynamics and the nature of IVR in the benzene ring are discussed and related to the experimental obse rvations.
