Precession-nutation torque in terms of the stokes constants

The precession-nutation torque of the earth-moon system is determined analytically for all degrees of spherical harmonics by combining and generalizing the standard approach of Melchior (1978) and the method of Bursa (1982, 1983). The results are given in terms of the Stokes constants of the earth. The classical and Bursa methods are shown to give the same correct results for the total torque, but only the Bursa approach correctly differentiates the partial torques.
