The total energy of the electrons thus is a functional of the nuclear coordinates ;
when this energy is added as a potential energy to H . - n , the resulting
Hamiltonian then depends only on the nuclear coordinates Rg . In a second step
this ...

However , if more than one nuclear spin is coupled to an electron spin , the
situation changes . For N equivalent nuclear spins ( I = 1 / 2 ) coupled to an
electron , there are at least ( N + 1 ) ESR lines , but only two NMR ( ENDOR )
lines ...
