Adsorption isotherms at 77K have been studied. The induced infrared activity of the N-N stretching vibration has been investigated as function of temperature and filling fraction. Molecules in the first monolayer next to the pore walls can be discriminated from those in the second monolayer, whereas molecules in the center of the pores remain infrared inactive. © 1998 Plenum Publishing Corporation.en1573-735719981/21929Springer Science + Business Media B.V.PhysikJournal Article10.1023/a:1022528703716Other
