The forces constant for $\mathrm{H}^{35} \mathrm{Cl}$ and $\mathrm{D}^{35} \mathrm{Cl}$ are the same and both can be considered as harmonic oscillators. $\mathrm{H}^{35} \mathrm{Cl}$ has a fundamental vibrational transition at $2886 \mathrm{cm}^{-1}$. The ratio of the zero-point energy of $\mathrm{H}^{35} \mathrm{Cl}$ to that of $\mathrm{D}^{35} \mathrm{Cl}$ is
(d)1.946
(a)0.515
(b)0.717
(c)1.395
