Examination of cucurbit[7]uril and its host-guest complexes by diffusion nuclear magnetic resonance
Article Abstract:
Pulsed gradient spin-echo nuclear magnetic resonance spectroscopy is used for examining the self-diffusion of cucurbit[7]uril (CB[7]) and its host-guest complexes in [D.sub.2]O. Studies have shown that in most of the cases, encapsulation of a variety of inorganic and organic guests within CB[7] has decreased their rates of diffusion in [D.sub.2]O.

Magnetic orientation of 1,3,5-triphenyl-6-oxoverdazyl radical crystals
Article Abstract:
The magnetic orientation was studied for paramagnetic organic radical crystals 1,3,5-triphenyl-6-oxoverdazyl and 1,5-di-p-tolyl-3-phenyl-6-xoverdazyl. The X-ray diffraction measurement revealed that the crystals are oriented with the crystallographic c axis perpendicular to the field.
