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 …
