Authors: Misawa Hiroaki , Sakuragi Hirochika , Usui Yoshiharu , Tokumaru Katsumi 
Published: July 2006

Abstract
Eosin Y was not photobleached with triethanolamine (TEOA) on visible light irradiation in the presence of methyl viologen (Mv2+), and worked as an effective sensitizer to reduce Mv2+ into MV+· with TEOA in aqueous ethanol. The resulting MV+· reduced water to hydrogen in the presence of colloidal platinum in the same solvent. The quantum yield for MV+· formation was measured to be ca. 0.3.

INVESTIGATION OF THE FACTORS AFFECTING THE 29Si MAS NMR LINEWIDTHS OF ZEOLITES
Authors: Fyfe C A , Gobbi G C , Murphy W J , Ozubko R S , Slack D A 
Published: July 2006

Abstract
The study of 29Si MAS NMR spectra of zeolites of both low and high Si/Al ratios has provided insight on the factors affecting the residual 29Si line-widths of these materials. It is found that the residual linebroadening in low Si/Al ratio zeolites is due to the distribution of local environments of a particular Si(nAl) type, resulting from the distribution of aluminium atoms in second and further coordination spheres. This is complicated in some cases by a distribution of chemical shifts resulting from crystallographic inequivalence, each of which is subject to the above environmental broadening factors.

Authors: Yoneda Norihiko , Sato Haruhiko , Fukuhara Tsuyoshi , Takahashi Yukio , Suzuki Akira 
Published: July 2006

Abstract
In a HF–SbF5 solution at −20∼30 °C under atmospheric pressure, ketones having alkyl groups with five or more carbon atoms underwent the reaction to give corresponding oxo carboxylic acids without any β-scission processes which occur readily in alkyl cations derived by protolysis of alkanes with seven or more carbon atoms. Tertiary C–H bond located at δ or further away from the oxo group in the substrates could react exclusively to give (ω–1)-oxo-2,2-dimethyl carboxylic acids at −20 °C.
DETERMINATION OF SILICON-ALUMINIUM ORDERINGS IN MORDENITE AND ITS ALUMINIUM DEFICIENT FORMS USING HIGH-RESOLUTION MAGIC-ANGLE-SPINNING 29Si-NMR
Authors: Debras G , Nagy J B , Gabelica Z , Bodart P , Jacobs P A 
Published: July 2006

Abstract
A series of chemically dealuminated mordenites were investigated by 29Si and 27Al NMR spectroscopy. High-resolution magic-angle-spinning (HRMAS) solid state 29Si NMR lines with varying intensity were observed at δ=−95, −105 and −110 ppm. When it is assumed that the Al atoms are located exclusively in the 4-membered rings of the structure, these variations can be explained by assigning the resonance lines to silicon atoms surrounded by 2, 1 and 0 Al atoms respectively. The 27Al NMR spectrum yields quantitative information on the amount of octahedrally coordinated aluminium formed during various chemical treatments of Na-mordenite.
