Start with the most stable electron configuration.It corresponds with a state with maximal S and L. It is relatively easy to calculate the term symbol for the ground state of an atom. When it is odd, the parity of the term symbol is indicated by a superscript letter "o", otherwise it is omitted:Īlternatively, parity may be indicated with a subscript letter "g" or "u", standing for gerade (even in German) or ungerade (odd): In fact, only electrons in odd orbitals contribute to the total parity: an odd number of electrons in odd orbitals (those with an odd l such as in p, f.) will make an odd term symbol, while an even number of electrons in odd orbitals will make an even term symbol, irrespective of the number of electrons in even orbitals. Where l i is the orbital quantum number for each electron. The parity of a term symbol is calculated as 3 Term symbols for an electron configuration.In this case, J can be 1, 2, or 3, so 3 + 5 + 7 = 15. The sum of (2 J+1) for all levels in the same term equals (2 S+1)(2 L+1). A combination of L, S, J and M J determines a single state.Īs an example, for S = 1, L = 2, there are (2×1+1)(2×2+1) = 15 different microstates corresponding to the 3D term, of which (2×3+1) = 7 belong to the 3D 3 (J=3) level.A given level has a statistical weight of (2 J+1), which is the number of possible microstates associated with this level in the corresponding term A combination of S, L and J is called a level.The combination of an S value and an L value is called a term, and has a statistical weight (i.e., number of possible microstates) of (2 S+1)(2 L+1).In that last case, Greek letters are used to designate the (molecular) orbital angular momenta. The term symbol is also used to describe compound systems such as mesons or atomic nuclei, or even molecules (see molecular term symbol). When used to describe electron states in an atom, the term symbol usually follows the electron configuration, e.g., in the case of carbon, the ground state is 1s 22s 22p 2 3P 0. J is the total angular momentum quantum number. L is the total orbital quantum number in spectroscopic notation, 2 S+1 is the spin multiplicity: the maximum number of different possible states of J for a given ( L, S) combination. The ground state term symbol is predicted by Hund's rules. It is related with the energy level of a given electron configuration.
