The local structure of P-rich and Se-rich phosphorus–selenium glasses was studied using high-resolution31P solid-state MAS NMR. Two-dimensional31P homonuclear through-bond correlation MAS experiments and 2D homonuclearJ-resolved MAS measurements were performed at high spinning frequency to probe P...

The catalytic role of the cofactor phosphate moiety at the active site of glycogen phosphorylase has been the subject of many investigations including solution-state high-resolution 31P-NMR studies. In this study the pyridoxal phosphate moiety in both the inactive and active forms of microcrystalline...
Frequency-stepped ultrawideline (UW) 65Cu solid-state NMR (SSNMR) experiments have been performed on a series of nine bis(triphenylphosphine) copper(I) species, with eight of these having an oxyanion-based ligand and one a borohydride ligand. These copper atoms reside in spherically asymmetric en...
摘要: While P-31 solid-state NMR experiments are being carried out for DPPC vesicles mixed with trehalose, the spectra exhibit sudden changes, implying that during dehydration the trehalose molecules bind to the head groups of lipids.关键词: Congresses, Commercial policy, Economic policy ...
