In my thesis I shall focus on the development of new NMR experimental methods to study structure and internal motions of two kinds of biological polymers, viz. proteins and nucleic acids. I shall investigate the anisotropic local motions of peptide planes ...
The bimetallic ruthenium complex [(1,3,5-C6H3i-Pr3)Ru(m-Cl)3RuCl(C2H4)(PCy3)] has been synthesized by reaction of [(1,3,5-C6H3i-Pr3)RuCl2)]2 with one equivalent of PCy3 in the presence of ethylene. It can be used as a catalyst precursor for the controlled ...
A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...
Two-dimensional Fourier-transform techniques were used to observe the deuteron double quantum transition for DC.tbd.CCN and CDCl3 partially oriented in a nematic solvent. Obsd. linewidths agree well with those calcd. from appropriate spin-lattice relaxatio ...
A spectrometer allowing the measurement of signals with spin-spin relaxation times as short as 0.5 μs has been developed. It consists of a transmitter based on a commercial spectrometer and a homemade receiver. The acquired signals are imported in the soft ...
In this paper, we point out the specific aspects and difficulties of performing NMR of transition metal surfaces. We show how basic NMR techniques allowed us to determine molecular structures and rates of thermal decomposition of simple chemisorbed molecul ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale may well be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding of the ...
NMR spectroscopy is one of the newer spectroscopic techniques for investigating the static, dynamic and electronic structures of molecules adsorbed onto metal catalyst surfaces. We review recent progress in the application of solid-state NMR methods to the ...
The interface between solid surfaces and cavities filled with gaseous 131Xe can be probed by multiple-quantum filtered NMR. Physisorbed 131Xe is usually not directly observable by NMR spectroscopy, but information can be transferred into the gas phase thro ...
