Part of the NATO ASI Series book series (NSSB, volume 272)


An accurate Moon’s rotation model has been performed by numerical integration. Direct gravitational perturbations on the Moon’s rotational motion have been analysed. Their resulting librations are presented in this paper including complete physical librations, planetary effects and Earth-Moon figure-figure interactions.
