La thèse est consacrée à l'analyse de la mobilité et de l'interaction du dihydrogène dans et avec des complexes de transition par la spectroscopie RMN à l'état gazeux, liquide et solide. Le sujet est traité en quatre chapitres indépendants. Dans le premier chapitre des études sur l'échange quantique de ligand dihydrogène dans les complexes synthétisés [RuCl(H)2(dppe)2]+[BF4]- (1), [OsH(H)2(dppe)2]+[BF4]- (2), et [RuH(H)2(dppe)2]+[BF4]- (3) ont été réalisées. Jusqu'à présent, il n'existe aucune méthode pour déterminer les fréquence de tunnelling rotateur expecter pour ces complexes dans la gamme des MHz. Ici nous avons utilisé comme méthode la relaxation en RMN à l'état solide en champ variable à basse température. Dans le deuxième chapitre,...
