The self-consistent reaction field

WebbThe existence of the N(3)–H isomer was supported by DFT calculations, taking into account solvent effects using the polarizable continuum model (PCM) and Poisson–Boltzmann self-consistent reaction field (SCRF-PB) models. NMR spectroscopy has been used to measure the levels of tautomerism of purines at temperatures of −60 … Webb14 apr. 2024 · The models take into account multiple fields in their mutual non-linear interactions: the complex order parameter, the self-consistent electric field, and the reaction of normal carriers. We explore the traditional time-dependent Ginzburg–Landau approach and introduce its generalization allowing the …

Douglas Hartree's methods were guided by some earlier, semi-empirical methods of the early 1920s (by E. Fues, R. B. Lindsay, and himself) set in the old quantum theory of Bohr. In the Bohr model of the atom, the energy of a state with principal quantum number n is given in at…
