Abstract. The photodissociation is an important elementary process in the interaction of light with molecules.

In the investigation of the dynamics of the photodissociation special attention has been directed to the question how the excess energy is distributed among the dissociation products and among their different degrees of by: 1.

The paper presents the results of a numerical evaluation of limiting sensitivity of the method for detecting vapors of nitrocompounds in the atmosphere based on one-color laser fragmentation (LF)/laser-induced fluorescence (LIF) of NO fragments via A2Σ+ (v′ = 0) ← X2Π (v″ = 2) transition.

The calculations were performed using the developed kinetic model of the one-color LF/LIF Author: Sergei Bobrovnikov, Evgeny Gorlov, Viktor Zharkov. Photons are tiny bits of light and other kinds of electromagnetic s can sometimes break apart molecules. When this happens, it is called photodissociation.

When a photon runs into a molecule, it adds energy to the les have chemical bonds that hold the atoms in them together with each other. If the chemical bond breaks, the molecule falls apart. Vibrationally mediated photodissociation, in which one photon prepares a highly vibrationally excited molecule by vibrational overtone excitation and a second.Download Richard N.
