Selective Dissociation of Polyatomic Molecules by Two Infrared Pulses

摘要: Recently, the collisionless multiple photon dissociation of polyatomic molecules by infrared lasers has become one most interesting and intriguing problems in laser physics chemistry. The possibility that an isolated molecule, placed intense field a laser, can absorb many photons (enough to dissociate as result absorption) very short time span, was first suggested 1971 Isenor Richardson [1] based on their observations studies prompt luminescence which observed focal near volume lens focused IR radiation into absorption cell. Interest this phenomenon heated observation process under certain conditions is isotopically selective [2,3]. In these reports, extremely large enrichment factors boron sulfur isotopes were reported. Later, results successfully duplicated laboratories [4,5].
