Description
  • Rychlostní konstanty překlápění pole vodíkových vazeb byly stanoveny v teplotním rozsahu 221–304 K pomocí NMR měření závislosti příčné relaxace kvartérních jaderných spinů 13C na efektivním radiofrekvenčním poli. Rychlostní konstanty leží v intervalu 1.4x0102-.2x04s-, hodnota aktivační entalpie je 36.8 kJ/mol a aktivační entropie je -6 J mol- K-. (cs)
  • The rate constants of reversal of the array in the temperature range of 221–304 K were determined by means of the NMR measurements of quaternary 13C nuclear spin transverse relaxation dependence on the effective radio frequency field. The flip-flop rate constants are in the range of 1.4x102-.2x104s-1, the activation enthalpy is 36.8 kJ/mol, the activation entropy is -36 J mol- K-1.
