The onset temperature $T_{\text{m}}$ and the Vogel-Fulcher temperature $T_{0}$ were determined for the structural glass Rb1-x[N(H1-yDy)4]x(H1-yDy)2PO4 ($x{=}0.5$, $y{=}0{\sim}1.0$) by the measurement of the complex dielectric constant. The values of $T_{\text{m}}$ and $T_{0}$ increase markedly with the deuteration rate $y$. It is found that the polydispersive nature of the dielectric dispersion becomes appreciable below $T_{\text{m}}$. The breadth of the relaxation time distribution increases as temperature approaches $T_{0}$.
