WebJun 11, 2010 · The electronic states of atoms and molecules depend on the symmetry imposed by their local environment. A simple manifestation occurs in the attachment of ligands to a transition-metal ion to form a coordination complex, which breaks spherical symmetry and causes splittings within the ion’s initially degenerate d orbitals. For a … WebWhen a reactant exists in one spin state and the product exists in a different spin state, the corresponding reaction will have an increased activation energy when compared to a similar reaction in which the spin states of the reactant and product are isomorphic. b \u0026 b in pinelands cape townWebb) Symmetric orbital and antisymmetric spin part $\downarrow\uparrow-\uparrow\downarrow$ From here we can see that symmetric spin part of wavefunction gives rise to three different states — these are triplet states. If spin part of wavefunction is antisymmetric, there's only one such state — it's the singlet state. expieran.com log in
