The extended Hückel method is a semiempirical quantum chemistry method, developed by Roald Hoffmann since 1963. It is based on the Hückel method but, while the original Hückel method only considers pi orbitals, the extended method also includes the sigma orbitals. The extended Hückel method can be used for determining the molecular orbitals, but it is not very successful in determining the structural geometry of an organic molecule. It can however determin… WebThe temperature-dependent form of the extended Debye-Hückel equation is log (𝛾)= (−1.825×106) (𝜖𝑇)−32𝑧2𝜇⎯⎯√1+𝛼𝜇√2.00𝜖𝑇√ where 𝛾 is the activity coefficient, 𝜖 is the dielectric constant of water (a unitless quantity), 𝑇 is the temperature (in Kevin), 𝑧 is the charge of the ion, 𝜇 … rtog acute morbidity grading https://edgeexecutivecoaching.com
