Nonextensive Contributions to the Effective Action of an Ensemble of Chemically Non-Interacting H₂O Molecules Enclosed in the Cavity of Nanoscale SiO₂ Pores

The absorption spectra of water molecules enclosed in cavities of nanoscale silicon pores have been experimentally recorded. Experimental data have been interpreted within the framework of the approximation of absorption spectra by Gaussian-type contours. Experimental dependences of the intensity of these contours on the pore size are obtained. To interpret this dependence for the contour corresponding to chemically noninteracting particles, the mathematical apparatus of the analytical description of the thermodynamic ideal gas properties is used. The position of the extremes of the experimental curve is accurately described with the appropriate choice of the approximation parameter of the model under consideration.
