High-field 2D NMR studies of mortonins were performed at 500 MHz (1H) and 125 MHz (13C). Unambiguous assignment both of the 13C data to the carbon skeleton and that of the proton chemical shifts in these molecules was achieved, together with the esta

Synthetic alamethicin analogs, in which all Aib residues had been replaced by Leu (L2) then proline 14 replaced by an alanine (L5), were studied in SDS micelles using circular dichroism and NMR spectroscopy. Nuclear Overhauser effects were used as co

Binuclear lanthanide(III)-silver(I) β-diketonate chelates are effective NMR shift and relaxation reagents for substrates containing one or two multiply bonded nitrogen atoms, despite the fact that some of the substrates are able to react with lantha

The simplest methods of 2D δ-δ correlated spectroscopy (COSY and COSY LR) allow the easy observation of long-range coupling interactions. It is shown how these methods can lead to the discrimination between different pathways across single bonds: 4

Organometallic rhodium(I) derivatives have been studied by 103Rh NMR. The chemical shift range extends from 609 ppm ([Rh.cp.cod]) to 2714.7 ppm ([Rh.fod.cod]). These results are supported by 13C and 31P NMR results, and give information about the bon

15N NMR spectroscopy was used to distinguish between isomers and to characterize some series of novel fused polyaza heterocyclic ring systems. Support for the assignments was provided by means of some INDO/S-SOS shielding calculations. Previously obs
