Linear Free Energy Relationships of the C-13 NMR chemical shifts in 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones
(Arkat USA Inc., 2009)
The C-13 NMR chemical shifts of the C2 carbon atom in the heteroaromatic nuclei of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones were determined in deuterated DMSO solution. For quantitative ...
Far-infrared spectroscopy of PbTe doped with iron
(Belgrade: Serbian Chemical Society, 2002)
Far infrared reflection spectra, at room and liquid nitrogen temperature, of PbTe single crystals doped with iron are presented. Plasma minima were observed at about 160 cm–1 and 180 cm–1 for room and liquid nitrogen ...
Contribution of marine and continental aerosols to the content of major ions in the precipitation of the central Mediterranean
