    We know that isotopes have the same number of electrons (and the number of neutrons is changed), this means that B_J and J will be the same for both isotopes. We start by measuring a_1, the coupling constant for the first isotope, from this a_1 we determine J= J_1 = mu_1 B_J/(I_1*a_1). Then we measure a_2, the coupling constant for the second isotope, we then determine mu2 = a_2 *I_2*J_2/(B_J) = a_2*I_2*(mu_1*B_J/I_1a_1)/B_J = a_2 I_2 mu_1/(I_1 a_1), which are all known or measured quantities.
