The rotational dynamics of a supercooled model liquid of rigid [formula presented] dumbbells interacting via a Lennard-Jones potential is investigated along one single isobar. The time-temperature superposition principle, one key prediction of mode-coupling theory (MCT), was studied for the orientational correlation functions [formula presented] In agreement with previous studies we found that the scaling of [formula presented] in a narrow region at long times is better at high-[formula prese...
