Abstract
The dynamic susceptibility of propylene carbonate in the moderately viscous regime above ${T}_{\mathrm{c}}$ is reinvestigated by incoherent neutron and depolarized light scattering, and compared to dielectric loss and solvation response. Depending on the strength of $\ensuremath{\alpha}$ relaxation, a more or less extended $\ensuremath{\beta}$ scaling regime is found. Mode-coupling fits consistently yield $\ensuremath{\lambda}=0.72$ and ${T}_{\mathrm{c}}=182 \mathrm{K},$ although different positions of the susceptibility minimum indicate that not all observables have reached the universal asymptotics.
