Light’s Particle-like Properties
• Energy is quantized into discrete bundles of energy
• Absorption spectra wavelengths are related to specific energy jumps between different energy levels
• Each line on spectrum is a result of a specific energy transition
Molecular Absorption
• More complicated than atomic
E = Eelect + Evib + Erot
Much more energy levels that can absorb radiation, spectrum appears broader
Molecular Absorption
Continuous spectra result from:1. Liquids or solids packed closely therefore they
are incapable of independent behavior2. Complicated molecules involving many closely
related energy levels so energy overlap exists3. When unquantized energy bombards
molecules in presence of solvent molecules, spectra broadens b/c many closely overlapping energies
