Abstract

In this research, the mechanism of Complex formation between the Catechol with the nitrate and hydrogen sulfate through the Hydrogen bond analysis has been investigated. All calculations have been performed by using the Gaussian09 software within the DFT-B3LYP functional and the 6/311++G(d, p) basis set. The thermodynamic parameters of the studied reactions have been fully calculated. NBO analysis showed a proper charge transfer through the H-bondsin Complexes. The stabilization energies E(2) have been computed for these Complexes and showed that the interaction energy for the HSO4-Catechol Complex is more than nitrate-Catechol. Also, Atoms in molecules, analysis has been done and electron density, Laplacian and the ratio of the kinetic energy density to the potential issue have been obtained. Based on this analysis, the electron density is maximum for the nitrate-Catechol in the first step and for the HSO4-Catechol in the second step. Quantum chemistry reactivity parameters of electronic chemical hardness, electronic chemical potential, and electrophilicity index have been investigated and the probable correlations have been analyzed.
