Abstract. In this chapter we review excitation and dissociation experiments performed with pulsed lasers at single infrared frequencies. The review treats five areas of this subject: data-reduction techniques, absorption experiments for a broad range of species, SF 6 absorption experiments, dissociation experiments for a broad range of species, and the effect of gas pressure on both.

However, in polyatomic molecules, such as the polyaromatics mainly investigated here, the interaction of laser radiation with the molecule leads to incoherent multiple photon excitation.

Search. Advanced. An investigation of multiple-photon phenomena which may occur during the interaction of certain polyatomic molecules with powerful infrared lasers is presented. The basic mechanisms involved in the multiple photon absorption (MPA) and multiple photon dissociation (MPD) in these molecules were elucidated.

During MPA some molecules absorb more than one photon, whose frequency is close to. of multiple photon excitation and dissociation dynamics on the appearance of the spectrum are extensively discussed. A mathematical model to account for the effects of anharmonicity is described.

It explains for instance, qualitatively, how the observed spectral response can vary (slightly).

In order to selectively excite and dissociate the desired isotope UF6 two beams with frequencies corresponding to the first and second energy excitation levels of this. The discovery of infra-red, multiple-photon absorption (IRMPA) and dissociation (IRMPD) in isolated polyatomic molecules raised great hopes that one could direct chemical reactions, since IRMPA allows one to put a great deal of energy directly into the nuclear motion of a polyatomic molecule through a specific vibrational degree of freedom.[ The phenomenon of the infrared multiple–photon excitation (IR MPE) and collisionless dissociation of polyatomic molecules was discovered in works [1,2].

Numerous works were carried out later aimed to clearify the mechanism of this process. This interest was stimulated by the fact, that the widths both of. Is multiphoton dissociation of molecules a statistical thermal process. Phys. Rev. Lett. 40, – (). Bagratashvili V.
