Some structural data obtained by these methods are also discussed in the following sections. The XANES spectra of organotin(lV) are usually not so informative. The advantages and disadvantages of EXAFS as a structural probe are discussed...

Actually, as demonstrated by Gross and Schnepp5, both the s-cis and the s-trans chromophores possess many other electronic transitions down to 140 nm. However, the near-UV part of the spectrum has been the most studied and only the lowest energy transition has been used as a structural probe to solve conformational and configurational...

These traps, (Fig. 6) and similar effects in the motion of holes and other charges through polymers, would eventually be correlated also with such structural probes as positron lifetimes in macromolecular solids. Extensive recent studies of positron lifetime are based on positronium decay. In this, the lifetime of o-positronium (bound positron-electron pair with total spin one) is reduced from about 140 nanoseconds to a few nanoseconds by "pick-off annihilation" in which some unpaired electron spins in the medium cause conversion quenching of orthopositronium to para-positronium. The speed of the t2 effect is supposed, among other things, to represent by pick-off annihilation the presence of defects in the crystalline lattice. In any case, what amounts to empty space between molecules can then be occupied by orthopositronium.(14,15,16) It is now found in linear polyethylene, by T. T. Wang and his co-workers of Bell Laboratories(17) that there is marked shift in positron lifetimes over the temperature range of 80°K to 300°K. For... 

Dendrimer templated Pt-Au catalysts are also active for the selective catalytic reduction of NO by propylene in the presence of excess O2. In addition to its commercial importance, this reaction is particularly interesting for the Pt-Au system. Previous work with cluster-derived Pt-Au catalysts has demonstrated that this reaction exhibits structure sensitivity, suggesting that it may be possible to use it as a structural probe for Pt based catalysts. ...
