Investigation of multiple photon excitation of OsO₄ by dissociation yield saturation

The multiple photon dissociation of OsO₄ molecules by IR laser radiation has been performed under the saturation of the dissociation yield. The absolute friction of the excited molecules, the excitation level and their frequency dependencies; the dissociation crossection and the frequency distribution of the excited molecules after excitation by the laser pulse have been obtained on the basis of these measurements. Some main features of the multiple photon dissociation of OsO₄ following from the obtained characteristics are discussed.
