For infrared light applied to molecules adsorbed to metals, the surface version of these statements predicts three distinct forms of Raman spectral behavior.
For infrared light applied to molecules adsorbed to metals, the surface version of these statements predicts three distinct forms of Raman spectral behavior. Processes that violate these statements are generally derived by finding the expected value of the off-diagonal matrix elements of a system's Hamiltonian similar to finding the first order perturbation energies between two different states. The symmetry of that is then used to find where the expected value is non-zero to determine these statements. In the dipole approximation for a hydrogen-like atom, these statements imply that angular momentum must change between two different states. (*) Fermi's Golden Rule gives the rate for the processes that these statements apply to, and Laporte names one of these. Transitions between two states that violate these are called forbidden. For 10 points, name these quantum mechanical rules that govern what transitions are possible.
