Chapter 11, Problem 11.34E

An $\text{O}-\text{H}$ bond has a frequency of $3650{\text{cm}}^{-1}$. Using equation 11.27 twice, set up a ratio and determine the expected frequency of an $\text{O}-\text{D}$ bond, without calculating the force constant. $\text{D}=\text{deuterium}\left({}^2\text{H}\right)$. Assume that the force constant remains the same.
