A researcher is studying cytochrome oxidase, a protein that uses iron to bind diatomic oxygen. She collects two IR spectra, shown below. In the first spectrum, no isotopic labeling is used (top). In the second, $^{16}\text{O}$ has been replaced with $^{18}\text{O}$ (bottom).### Graph DescriptionThe two infrared (IR) spectra display percentage transmission on the y-axis and wavenumber ($ \nu_0 $ in cm$^{-1}$) on the x-axis, ranging from 600 to 850 cm$^{-1}$.#### First Spectrum (Top)- Peaks are observed at: - 655 cm$^{-1}$ - 695 cm$^{-1}$ - 714 cm$^{-1}$ - 733 cm$^{-1}$ - 790 cm$^{-1}$ - 820 cm$^{-1}$#### Second Spectrum (Bottom)- After replacing $^{16}\text{O}$ with $^{18}\text{O}$, peaks are found at: - 655 cm$^{-1}$ - 695 cm$^{-1}$ - 714 cm$^{-1}$ - 733 cm$^{-1}$ - 755 cm$^{-1}$ - 820 cm$^{-1}$### Questiona. Give the frequency shift (in Hz) that occurred when $^{18}\text{O}$ was substituted for $^{16}\text{O}$.
