Natural population analysis npa charges
Web5 de jul. de 2015 · The effect of solvents on the tautomeric stability has been investigated. Mulliken Population Method and natural population analysis (NPA) have been studied. NBO analysis is carried out to picture the charge transfer between the localized bonds and lone pairs. The local reactivity of the molecule has been studied using the Fukui function. Webnatural population analysis (NPA) The analysis of the electron density distribution in a molecular system based on the orthonormal natural atomic orbitals. Natural populations, are the occupancies of the natural atomic orbitals. These rigorously satisfy the Pauli exclusion principle:. The population of an atom is the sum of natural populations
