  We have investigated the electronic excitations in bulk 2H-MoS2 using
electron energy-loss spectroscopy. The electron energy-loss spectra in the
{\Gamma}M and {\Gamma}K directions were measured for various momentum transfer
values. The results allow the identification of the A1 and B1 exciton peaks and
in particular their energy-momentum dispersion. The dispersions exhibit
approximately quadratic upward trends and slight anisotropies in the {\Gamma}M
and {\Gamma}K directions. The fitted energy-momentum transfer functions allow
the estimation of the effective masses of the excitons which are in close
proximity to predicted values.
