Chapter 2, Problem 2.7P

The Rydberg constant equation has two terms that vary depending on the species underconsideration, the reduced mass of the electron/nucleus combination and the charge of thenucleus (Z).
a. Determine the approximate ratio between the Rydberg constants for isoelectronic ${\text{He}}^{+}$ (consider the most abundant heiium-4 isotope) and H. The masses of the electron,proton, and that of the ${\text{He}}^{+}$ nucleus ${\text{He}}^{\text{2}}$ is an $\alpha$ ) are given on the inside back cover of thistext.
b. Use this ratio to calculate an approximate Rydberg constant (J) for He.
c. The difference between the ${\text{He}}^{+}$ 2s and is orbitais was reported as $\text{3291 79}.\text{76197}\left(\text{2}0\right){\text{ cm}}^{-\text{1}}$ . Calculate the ${\text{He}}^{+}$ Rydberg constant from this spectral line for comparison to yourvalue from b.
