Sci., 2017, 8, 6570–6576] showed for R-substituted benzenes with R = NH2, NO2 that the substitution effects on the 13C NMR chemical shifts are correlated with changes in the σ-bonding framework and do not follow directly the electron-donating or -withdrawing effects on … "Reproduced from" can be substituted with "Adapted from".

In questi esperimenti i nuclei 13C sono eccitati da una serie di impulsi sia a frequenza 13C che 1H, ed il risultato è che i CH3, i CH2, i CH ed i C non protonati sono eccitati in maniera diversa l’uno dall’altro.

Five basis sets of gaussian functions have been developed to calculate magnetic properties of the benzene molecule within the framework of a coupled Hartree-Fock (CHF) approach exploiting the entire D6h symmetry.

The linewidth remains small despite the very strong direct dipole-dipole interactions that could be observed in some cases. It was found Δσ = σ. << do not need to formally request permission to reproduce material contained in this The intensities of the spinning side bands have been shown to contain information on the sign and the magnitude of the order parameter(s).
