Predicting the 1H and 13C NMR spectra of paramagnetic Ru(III) complexes by DFT

A fair agreement with experimental values is observed. Structural, magnetic and dynamic parameters have also been input to the Solomon?Bloembergen equation in order to predict signal lineshapes. It is shown that DFT?

Inside Cover: A Minimalist NMR Approach for the Structural Revision of Mucoxin (Chem. Eur. J. 46/2010)

Puzzle solved When the spectra of the synthesized structure of mucoxin, a natural product from the Annonaceous acetogenin family, did not match that of the isolated sample, the reason was not as obvious as one might hope.

Direct Evidence for the Nonrandom Nature of Al Substitution in Zeolite ZSM‐5: An Investigation by 27Al MAS and MQ MAS NMR

Incorporation of Al atoms in particular sites in the ZSM?5 structure is governed by the Si/Al ratio during synthesis, and their distribution over the twelve types of tetrahedral sites (T1?

The Leiodolide B Puzzle

Out of options? Even though a systematic approach was chosen, which led to a set of four diastereomeric macrolides modeled around the proposed structure of leiodolide?B (see picture), the puzzle concerning the stereostructure of this cytotoxic metabolite derived from a deep?

GIAO DFT 13C/15N chemical shifts in regioisomeric structure determination of fused pyrazoles

The combined use of two-dimensional NMR correlation experiments and gauge including atomic orbital density functional theory in 13C NMR chemical shift (CS) calculations allowed reliable and simple structural determination of regioisomeric heterocyclic systems that originate from the reactions of

Local Disorder in Hydrogen Storage Compounds: The Case of Lithium Amide/Imide

mides and imides of alkali metals are a very promising class of materials for use as a hydrogen-storage system, as they are able to store and release hydrogen via a chemical route at controllable temperatures and pressures.

Direct Structural Comparison of a Rigid Cyclic Peptidic Scaffold Using Crystallography and NMR in Strained PH Polymer Gels

mall series of biaryl ether containing cyclic peptidic scaffolds was synthesized and cyclized by an SNAr reaction. The structure of one rigid scaffold was solved by X-ray crystallography and also determined in solution by NMR spectroscopy.
