The complete assignment of the 13C NMR spectra of six aryl diazinyl ketones and twelve aryl diazinyl ketoxime ethers was carried out. 13C chemical shift differences of the a-carbon atoms were used to assign the configuration at the CN double bond of the oxime ethers.
The total assignment of the 13C NMR spectra of novel diazine derived ureas and thioureas is reported.
## Abstract ^1^H and ^13^C NMR studies were carried out on benzanthrone and 3β, 4β, 6β, 8β, 9β, 10β and 11βchlorobenzanthrone. Complete assignments of proton and carbon resonances were made with the aid of HHβCOSY, NOESY, CHβCOSY and HMBC techniques. Substitution effects of a chlorine atom are not
The complete assignment of the proton and carbon NMR spectra for ikarisoside A and epimedoside C from the aerial parts of Epimedium koreanum were achieved using the concerted application of one-and two-dimensional NMR techniques including COSY and HMBC spectroscopy. The parameters previously reporte
