1. Chemical State

   Linked via "molecular systems"

   $$
   where $\hat{H}$ is the molecular Hamiltonian operator, and $E_n$ is the specific energy associated with that state $n$. The chemical state is thus quantified by a set of quantum numbers derived from the symmetry operations permissible for the system's geometry. For molecular systems, these numbers dictate the electronic configuration, [vibrational …
