    Description / Table of Contents: Abstract The rotation of the Moon about its center of mass, taking into account the orbital motion, is treated analytically. A Hamiltonian theory is developed in terms of the Andoyer variables. The periodic parts of departures from three resonances, equivalent to Cassini's laws, are found to be the canonical variables of the problem. The potential is expressed as a function of these new coordinates and the whole Hamiltonian is developed to the second degree in these small variables. One system of equations gives the real center of libration which is found to be near the center defined by Cassini's laws. A second system solved by iterations, gives the libration as analytical series in the constants of the Moon's potential, and trigonometric series in Delaunay arguments. The question of convergence is briefly exposed without any demonstration.
    Notes: Résumé La rotation de la Lune autour de son centre de gravité est traitée par une méthode analytique, en tenant compte de son mouvement orbital. On développe une théorie Hamiltonienne en utilisant les variables d'Andoyer et l'on démontre que les écarts, purement périodiques, à trois relations de résonances similaires aux lois de Cassini, sont les variables canoniques du problème. Le potentiel est exprimé dans ces nouvelles coordonnées et l'Hamiltonien est développé jusqu'au deuxième degré en les petites variables. Un système d'équations donne le vrai centre de libration qu'on trouve proche du centre défini par les lois de Cassini. Un second système, résolu par un processus d'iterations, donne les séries de la libration, analytiques par rapport aux constantes du potentiel de la Lune et trigonométriques en les arguments de Delaunay. La question de convergence est brièvement abordée, mais sans démonstration.

    Notes: Abstract We have developed a theory of the rotation of the Moon, for the purpose of obtaining libration series explicitly dependent upon lunar gravitational field model parameters. A nonlinear model is used in which the rigid Moon, whose motion in space is that of the main problem of lunar theory, and whose gravity potential is represented through its third degree harmonics, is torqued by the Earth and Sun. The analytical series are then obtained as Poisson series. Numerical comparisons with Eckhardt's solution are briefly exposed.
