X-ray Crystallography:the closest we can get to photographing our molecules! • single crystal (not a powder or many tiny crystals) • periodic array of atoms symmetrically oriented • produces accurate (almost) bond distances and bond angles • The method: • see U.Penn X-ray Facility • see on-line X-ray Course • see illustration of Space Group Symmetry • one of my old structures (on Cu)
