The result, recently discovered by Forster, that the strength factors of the non-propagating modes in certain hydrodynamic correlation functions in nematic liquid crystals are not fully determined by the hydrodynamic matrix is reconsidered. Using time reversal and space inversion symmetry one finds that all the unspecified strength factors can be expressed in terms of three undetermined constants.L'objet du présent article consiste en un réexamen du résultat suivant récemment obtenu par Forster : dans le cas des cristaux liquides nématiques, il n'est pas possible de déterminer de manière complète, à partir de la matrice hydrodynamique, les amplitudes liées à tous les modes diffusifs. Nous montrons qu'à partir des lois de symétrie d'inversio...
