Simple Harmonic Oscillator - Classical and Quantum Descriptions SHO Charles Hermite French Mathematician 1822-1901 What do the following have in common? Hydrogen Nitrogen Oxygen Fluorine Clorine Bromine Iodine What do the following have in common? Hydrogen Nitrogen Oxygen Fluorine Clorine Bromine Iodine They all form diatomic molecules (H2 N2 O2 ……) See extra credit problem on HW #8 PHGN 300 Homework #8 (6 problems + 1 extra credit) 6) The harmonic oscillator potential is U(x)=1/mω02x2; a particle of mass m in this potential oscillates with frequency ω0. The ground-state wavefunction for a particle in the harmonic oscillator potential has the form ψ(x)=Aexp(-ax2) By substituting (Ux) and ψ(x) into the one-dimensional timeindependent Schrodinger Equation, find expressions for the groundstate energy E and the constant a in terms of m, ħ, and ω0. Extra Credit The H2 molecule can be approximated by a simple harmonic oscillator having spring constant k=1.1x103 N/m. Find (a) the energy levels and (b) the possible wavelengths of photons emitted with the H2 molecule decays from the third excited state eventually to the ground state. http://phet.colorado.edu/en/simulation/bound-states
