Recombination of carbonmonoxide after photodissociation has been studied by Mossbauer spectroscopy at 4.2K and in the low temperature region, where tunneling effects play an important role in rebinding. We interpret the kinetic results in terms of a radiationless nonadiabatic multiphonon transition, which leads to a uniform description for all temperatures. Prolonged illumination at low temperature results in pumping into long-living states.
