Abstract: The phonon dispersion is one of the most fundamental properties of a crystalline material. It determines virtually all of its physical properties, including optical, electronic, mechanical, and thermal behavior. Despite its importance, the phonon dispersion of MoS${}_{2}$ -- one of the most investigated two-dimensional semiconductors -- has not been determined experimentally in relevant parts of the Brillouin zone. In a combined experimental and theoretical approach, the authors present comprehensively the entire phonon dispersion of a MoS${}_{2}$ crystal and determine displacement patterns, symmetries, and scattering intensities.
