Teaching NMR spectra analysis with nmr.cheminfo.org
Teaching spectra analysis and structure elucidation requires students to get trained on real problems. This involves solving exercises of increasing complexity and when necessary using computational tools. Although desktop ...
Solvent effects on the infrared and 1h-nmr spectra of n, n'-thiodianilines
(1992)
The influence of various common basic solvents on the IR and 1H-NMR spectra of a series of N,N′-thiodianilines, , X = H, OMe, Br, Cl, and m-NO2 has been studied. The solvent shifts of both, frequencies θ(NH) and chemical ...
Complete assignment of the H-1 and C-13 NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole. Concerted use of one- and two-dimensional NMR techniques
(JOHN WILEY & SONS LTD, 1998-06)
The H-1 and C-13 NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole were totally assigned using a combination of one-and two-dimensional NMR ...
13C-NMR SPECTRA OF AZAFLUORENONES
(American Chemical Society, 1988-09-22)
The 13C-nmr chemical shifts of onychine (l-methyl4-aza8uoren-9-one) [l]
were assigned with the aid ofheternnuclear 2D-nmr spectraand these results were used to interpret
the 13C nmr spectra of several other synthetic duorenones.
Complete assignment of the 13C NMR spectra of 4,4-dimethylanthracene-1,9,10(4H)-trione and the regioisomeric monomethyl derivatives
(2000)
The 1H and 13C NMR spectra of a set of structurally related tricyclic quinones consisting of 4,4-dimethylanthracene-1,9,10(4H)-trione (1), 4,4,6,7-tetramethylanthracene-1,9,10(4H)-trione (2) and the regioisomers 4,4,5-(3), ...

(1998)
The 1H and 13C NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole were totally assigned using a combination of one-and two-dimensional NMR ...
Use of long-range C-H ((n)J n > 3) heteronuclear multiple bond connectivity in the assignment of the C-13 NMR spectra of complex organic molecules
(BENTHAM SCIENCE PUBL LTD, 2001-03)
The structural elucidation of complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment is probably the most useful 2D NMR method The ...
