Recall the selection rules for purely rotational microwave spectra: ΔJ = ±1. This came from angular momentum conservation (a photon has spin angular momentum ħ). In Raman scattering, one photon comes in and one photon goes out. What are the selection rules for rotational Raman transitions? (A) ΔJ = ±1 (B) ΔJ = 0, ±1, ±2 (C) ΔJ = 0, ±2 * (D) ΔJ = 0 This is because a photon comes in and transfers one unit of ħ to...
Selection rules and allowed transitions: Electron in a hydrogen atom is in 4p state. The energy level diagram is shown below. Note the energies are given to first decimal place only. (a) Draw arrows showing all the allowed transitions the 4p electron can make that lead to the emission of photon. Include all the transitions until the electron reaches the ground state. (b) What are the kinetic and potential energies of the electron in the 4p state? (c) Calculate the wavelengths (in nm)...

Activity Manual 22 on Photons does not discuss the momentum of a photon, but the photon’s momentum and momentum conservation are important for Positron Emission Tomography, a medical imaging technique that you will be studying in class soon. So in this homework you will learn about photon momentum and momentum conservation in the context of photon emission from hydrogen atoms. To remind you, in Physics 101 you learned that the momentum ~p of an object with mass m traveling with...
A certain molecule has a characteristic rotational energy of 8.26x10-4 eV. What is the energy of the decay photon towards the state with angular momentum quantum number l = 9? Note: The selection rules of delta l = +/- 1 tell you to what state it can decay. Please show work.
