|Theoretical chemistry deals in providing explanations to chemical and physical observations. Theoretical chemistry includes the fundamental laws of physics Coulomb's law, Kinetic energy, Potential energy, the Virial Theorem, Planck's Law, Pauli exclusion principle and many others to explain but also predict chemical observed phenomena. Chemical Sciences journal is one of best Open- Access journals in Theoretical chemistry. The journal publishes regular articles reporting original work. Such articles contain full details of the theory and/or computations. OMICS Group International through its Open Access Initiative is committed to make genuine and reliable contributions to the scientific community. OMICS Group hosts over 700+ peer-reviewed journals and organize over 3000+ International Scientific Conferences annually all over the world.
