Chemistry 111 Fall, 2005 Prof. Simpson Chemistry 111 Handout #7 Impress your Family and Friends by Drawing Wavefunctions The wavefunction Ψ is just an expression that describes the molecular orbitals we already know and love (e.g. 1s, 2s, 2p, etc.). Knowing the shapes of the wavefunctions is important because that's what determines the molecules atoms build and how they react. Think about how differently you would have to build things if rectangular bricks were shaped like ovals. Same idea here. Remember, we cannot "see" the wavefunction, really. What we see are probabilities = the mathematical square of the wavefunction. Ok … so the steps to drawing a wavefunction are quite straightforward. Steps to Drawing a Wavefunction . 1. What is the orbital you are supposed to draw? (e.g. 2p x , 5s, etc.) 2. What is the quantity you are supposed to draw? Æ radial probability distribution function is the r 2 R 2 vs r. It describes the probability of finding an electron some distance from the nucleus, without regard to direction. It also gives us the
