## Abstract Rotational barriers in 21 __p__‐ and __m__‐substituted __N__,__N__‐dimethylbenzamides in CDCl~3~ as solvent have been determined using the intensity ratio method of Woodbrey. These data compare very well with values from the literature^1^ obtained with a total line shape analysis. From

1H magic-angle spinning nuclear magnetic resonance (MAS NMR) spectra of TiO chi/SiO2 catalysts suggest the interaction of surface TiO chi species with Si-OH groups of the silica. Simultaneously, Ti-OH groups from surface titania species appear. The distribution of TiO chi species over SiO2 is non-un
