SPECTROSCOPIC PROPERTIES OF HYDROPHOBIC FLAVIN ESTERS.: A ONE AND TWO-DIMENSIONAL ¹H-NMR AND 13C-NMR STUDY
(Sociedad Chilena de Química, 2000)
13C-NMR spectroscopy of para-substituted benzylideneacetones. I. Long distance electronic effects
(Marcel Dekker Inc., 1997)
Para-benzylideneacetones present a characteristic long distance charge transfer pattern, where the olefinic bridge (CH=CH) and the aromatic ring (Ph) carbon centers are perturbed according to the nature of the para-substituent ...
13C-NMR ano theoretical stuoies of internal rotation in methylateo anillnes
(Socieda Chilena de Quìmica, 1997-08-01)
The conformational properties of ten ring-methylated N-methyl- and N,Ndimethylanilines
have been studied using 13C-NMR chemical shifts and spin-Iattice
relaxation times in CDCI3, and semi-empírical (AM1) quantum-chemical ...
13C-NMR and theoretical studies of internal rotation in methylated anilines
(1998)
The conformational properties of ten ring-methylated N-methyl- and N,N-dimethylanilines have been studied using 13C-NMR chemical shifts and spin-lattice relaxation times in CDCl3, and semi-empirical (AM1) quantum-chemical ...
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.
13C-NMR spectroscopy of β-nitrostyrenes. II 11. Mono-, bi- and tri-methoxy phenyl-substitutions and long distance electronic effects
(Marcel Dekker Inc., 2000)
By means of 13C-NMR spectroscopy and AM1 molecular orbital calculations of mono-, bi- and tri-methoxy-β-nitrostyrenes at the meta and para positions, we have characterized a long distance electronic charge transfer pattern ...
THE 13C-NMR SPECTRA OF 1,2,10-TRIOXYGENATED APORPHINES

Chemical composition from volatile oil of the stem bark of Guarea macrophylla Vahl. ssp. tuberculata Vellozo (Meliaceae)
(2002)
The stem bark of Guarea macrophylla Vahl. ssp. tuberculata Vellozo (Meliaceae) was submitted to steam distillation and adsorption chromatographic separation. Seventeen sesquiterpenes, one diterpene and four fatty acids ...
