On molecular orientability on a fine porous surface

2014 The refraction of a porous structure with adsorbed molecules was investigated. Effects based on adsorbate molecule orientability relative to the whole porous sample were evidenced including quantitative estimates of the adsorbate molecule amount in pores. In a resonance electromagnetic field, sharp changes in the permeability of a fine-pored sample were observed corresponding to a variation in the incident laser intensity. Finally, a theory of the orientational action of the radiation field was developed, which accounts for the adsorption potential increase not only by the interaction of field polarized molecules with those on the surface, but also by the interaction of the induced molecular dipole with its reflection in the wall material.
