✦ Synopsis

A mechanism for ,I rollrs~onlc~s drctocLtmn of a polyatomic molecule via sequential Incoherent absorption of Infrared photons is examined. The proposed mechanism has known analogs for macroscopic systems and c\htbtts the followmg charactcristics. The operation II thrc4lold is govcrncd by thr ,a~l~c cncrgy (and not by the peJk power). For a given pulse duration il rno~cculc with 3 hlghcr anharmonlc Loupling wrll require a lower threshold power for dis\oaation. Past the threshold the dissocintdon efficiency can approach B limiting value of very nearly umty and the dissociation p:oducts wdl bc internally cxcitcd.
