The quantitative analysis of MAS-NMR spectra was carried out with the Winfit software package (Bruker). This program allows the position, linewidth, and intensity of components to be determined with a nonlinear iterative least-squares method. However, quadrupolar CQ and η constants must be ...
Ketalisation with 4- t -butyl-cyclohexanone leads to a "semimobile" structure of a trispiro-1,3-dioxane in which the two marginal cyclohexanic rings are fixed, while the two middle ones are mobile, continuously flipping at room temperature. The solvent effect on the NMR spectra is also ...
Vibrational effects on NMR shielding constants and nuclear spin–spin coupling constants have been investigated in a model hydrogen-bonded complex, CNH:NCH. Expectation values of the spin–spin coupling constant 2 h J N– N, obtained from a two-dimensional EOM–CCSD/(qzp,qz2p) surface, and ...
