“…In the liquid phase TV,TV-dimethylcarbamyl bromide, chloride, and fluoride have AG*298 values for the internal rotation process of 15.7, 16.8, and 18.1 kcal/mol, respectively. 7 In an 18 mol % solution in sym-tetrachloroethane, TV,TV-dimethylcarbamyl cyanide has *298 for its internal rotation process of 21.4 kcal/mol.7 For TV.TV-dimethylcarbamyl azide it is 17.7 kcal/mol. This observation has been explained on the basis of cross conjugation effects.…”

Temperature-dependent gas-phase 'H NMR spectra of six C-substituted TV,TV-dimethylamides (XCON(CH3)2) obtained at 500 MHz are consistent with the following free activation energies, AG*29i (kcal/mol): X = Cl, 15.4 (0.2); Br, 14.1 (0.2); N3, 16.5 (0.1); CN, 19.0 (0.1); CH2F, 15.2 (0.1); CHF2, 17.4 (0.1). For all of the amides studied, the observed first-order unimolecular rate constants are consistent with gas-phase <3*298 values for the internal rotation process which are 1-2 kcal/mol lower than reported condensed phase values and, in each case, consistent with a process proceeding via a transition state which has greater steric requirements than the equilibrium conformation.

“…Durante a década de 70, o campo de atuação da fotoquímica dos complexos de metais de transição cresceu rapidamente e em muitas direções [46,47,48]. Um passo significativo foi 8 a observação de que muitos compostos de coordenação apresentam estados excitados emissivos nos estados sólidos, vítreos e a temperatura ambiente em solução fluida.…”
