Dyes incorporated in molecular sieve crystals can reveal information about the orientation of guests in these crystals through polarization microscopy (see Figure), Raman scattering, and second‐harmonic generation measurements. Pyroelectric studies of the dye molecule para ‐nitro‐aniline inserted in the molecular sieve A1P0 4 ‐5 are described that show which of two rival models explaining the ordering of guests in molecular sieves actually holds.
