Analytical characterization and evaluation of performance of zeolite catalysts are normally done under the assumption of a homogeneous batch. However, it is known that in the same batch particles of the zeolite ZSM-5 can be very different one from another, regarding their aluminum content and catalytic performance.

A great wealth of structural information about phosphazenes can be gleaned from the combined spectroscopic and crystallographic data. When data from 31P NMR spectroscopy and X-ray crystallography are put together like pieces in a puzzle, a number of correlations can be obtained for phosphazene derivatives. A systematic study concerning the correlations among the structural parameters (e.g., 31P NMR data, endocyclic/exocyclic NPN bond angles and bond lengths) revealed some characteristics of mono- and di-spirocyclophosphazene derivatives bearing 4- fluoro/nitrophenylmethyl pendant arm/arms.

The results of a systematic study of spiro-cyclotri/tetraphosphazenes with ferrocenyl pendant arm on the basis of correlation between structural parameters were presented. The main parameters were obtained from Xray crystallography and 31P NMR results in order to investigate the relationship between the δPspiro shift values and endocyclic and exocyclic NPN bond angles, and electron density transfer parameters.

Apart from its numerous biological activities like antidiabetic, anti-infammatory, antimicrobial, pyrazine moiety plays an important role in luminescent materials. Its role in luminescent materials is due to its highly electron deficient nature specially when it is in the centre along the mainstay of extended π-conjugated systems.

Aspects of intramolecular light energy and electron transfer will be discussed for three protein-cofactor complexes, whose three-dimensional structures have been elucidated by X-ray crystallography: components of lightharvesting cyanobacterial phycobilisomes; the purple bacterial reaction centre; and the blue multi-copper oxidases. A wealth of functional data is available for these systems which allows specific correlations between structure and function and general conclusions about light energy and electron transfer in biological materials to be made.
