A lithium atom has mass and a hydrogen atom has mass The
Chapter 42, Problem 42.13(choose chapter or problem)
A lithium atom has mass \(1.17\times10^{-26}\mathrm{\ kg}\), and a hydrogen atom has mass \(1.67\times10^{-27}\mathrm{\ kg}\) The equilibrium separation between the two nuclei in the LiH molecule is 0.159 nm. (a) What is the difference in energy between the l = 3 and l = 4 rotational levels? (b) What is the wavelength of the photon emitted in a transition from the l = 4 to the l = 3 level?
