Transformation of two-photon impurity absorption spectra under conditions of dissipative tunneling in a quantum molecule

Influence of the dissipative tunneling parameters on dependence for the two - photon impurity absorption probability in quantum molecule, has been theoretically investigated. In is shown, that the tunnel barrier transparency influence on two - photon impurity absorption in quantum molecule is appeared in the energy levels width change for virtual and final states, because of variation of such dissipative tunneling parameters as temperature, local phonon frequency and the interaction constant with a heat bath.
