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