Unformatted text preview: Chem 120A Why chemistry needs quantum mechanics 08/27/2010 Fall 2010 Lecture 1 Why is quantum mechanics important for chemistry? 1. Stability of matter the stability of atomic and molecular structure cant be explained classically. 2. The photoelectric effect light is quantized. 3. Black body radiation matter has quantized energy levels. 4. Molecules the stability of the chemical bond is a quantum mechanical effect. 5. Quantum Optics lasers and spectroscopy (important to chemists!) can only be explained quantum mechanically. 6. Biology biology is dependent on the structure and reactivity of molecules. Also quantum coherence is relevant e.g. in photosynthesis. 7. Quantum entanglement, non-local correlations due to quantum statistics, teleportation and other Quan- tum Spookery. Black body radiation Lets say you have a solid body (the black body) at high temperature which emits radiation. Classical theory predicts that ( , T ) d = 8...
