Solvent effect on the tautomers' stabilities of protonated N,N‐dimethylnitrosamine: The role of hydrogen bonds network

Abstract: DFT calculations have been applied in order to study the free energies of the structures corresponding to the three different protonation sites of N,N‐dimethylnitrosamine (DMNA). The solvent effect has been taken into account through the study of clusters consisting of protonated DMNA and up to four explicit water molecules, either in the absence or in the presence of a continuum (CPCM) solvation model. Addition of water molecules has been done by a careful screening procedure through which all important hydro… Show more

“…The CPCM has been found to be a reliable continuum solvation model for bringing theoretical calculations closer to experimental results. [30][31][32][33] The zero-point energies (ZPEs) utilized for energy correction were obtained by calculating the vibrational frequencies of all species at the same basis set level. The free energies (G) discussed in this work were the sum of the entropy correction (-TS 298 ), the ZPE correction (E ZPE , 0 K), the electron energy (E elect , 0 K), and the thermal correction (E corr , 298 K).…”
