Cette thèse, rédigée en anglais, est une étude théorique de collisions lentes atome-diatome et d'états vibrationnels du trimère près du seuil de dissociation. Elle est composée des chapitres suivants: I. Introduction. II. Mapped Fourier Grid. III. Quantum dynamics of a triatomic system. IV. Potential energy surface of the sodium trimer. V. Loosely bound vibrational states of the sodium trimer. VI. Prospects for the photoassociation of Na3. VII. Conclusion. Les parties originales du travail sont présentées dans les chapitres II et V. Le chapitre II concerne la méthode de grille de Fourier à pas variable. Cette méthode numérique permet de calculer des états vibrationnels de dimère proches des seuils de dissociation, mais souffre de l'appariti...
