Abstract
All unitary solutions of the weak-coupling gap equation for pairing are exhibited, and their rotational degeneracies highlighted. The role of the Zeeman and dipolar energies in resolving these degeneracies is examined. These interactions are used to calculate the NMR frequency, and the assumptions used by Anderson and Leggett in earlier calculations are clarified. In particular, "classical" equations are given which are equivalent to Leggett's quantum-mechanical analysis.
