Abstract
Zeolite-like molecular sieves are characterized by a regularly arrange d micropore system. These pores can order adsorbed molecules. The resu lting guest-host composites are promising materials for spectroscopy b ecause of the non-random orientation of the transition matrix elements . By studying the Raman scattering of p-nitroaniline (PNA) within a la rge aluminophosphate AlPO4-5 crystal, it was found that the PNA molecu les are very well aligned inside the pores, forming dipole chains with intermolecular interactions as in the solid.
