    2021-6-2 · Coupling Schemes and Term Symbols The coupling schemes outlined above include those now most frequently used in calculations of atomic structure . Any term symbol gives the values of two angular momenta that may be coupled to give the total electronic angular momentum of a level (indicated by the J value). For configurations of more than one unfilled subshell, the angular momenta involved in the final coupling …
