AClassical Description E = T + V E = ½mv 2 + ½kx 2 B QM description - the Hamiltonian H v = E(v) v CSolve the Hamiltonian - Energy Levels G(v) = ω(v+ ½) (cm -1 ) DSelection Rules - Allowed Transitions v = ±1 ETransition Frequencies > G = ω FIntensities - THE SPECTRUM J Analysis - Pattern recognition; assign quantum numbers HExperimental Details - spectrometers, lasers IMore Advanced Details: anharmonicity JInformation: potential, force constants, group identification Harry Kroto 2004
