Abstract
A mechanism for a collisionless dissociation of a polyatomic molecule via sequential incoherent absorption of infrared photons is examined. The proposed mechanism has known analogs for macroscopic systems and exhibits the following characteristics. The operational threshold is governed by the pulse energy (and not by the peak power). For a given pulse duration a molecule with a higher anharmonic coupling will require a lower threshold power for dissociation. Past the threshold the dissociation efficiency can approach a limiting value of very nearly unity and the dissociation products will be internally excited.
