  We present the first three-dimensional calculations of Radiation Driven
Implosion of Molecular Clouds including self-gravity and ionization. We discuss
the effects of initial density perturbations on the dynamics of ionizing
globules and show that the onset of gravitational collapse can be significantly
delayed for a multiple of the implosion timescale. We demonstrate that
Radiation Driven Implosion could be an efficient process for injecting
disordered kinetic energy into molecular clouds in the vicinity of massive
stars.
