Document Summary

Chem 110 lecture 4 qm & the structure of molecular energy levels. Lecture date/time: sept 16th, 2015 / 10:35-11:25 am. (continued from lecture 3) Qm (quantum mechanics) & the structure of molecular energy levels. Goals: what do real energy levels look like, how de broglie describes particles as waves, to try and understand how wave-like" molecules translate, rotate, and vibrate. Louis de broglie suggested that light and matter both behave like waves. Erwin schrodinger added to de broglie"s idea of particles as waves and then generalized a standing wave equation for all matter. In class: imagine a guitar string, attached at both ends, while someone plays the guitar: the string would look like several wave vibrations. ^standing waves (=a vibration of a system/wave in which some particular points remain fixed while others between them vibrate) self-reinforce and exist," and the square of each wavefunction is physical reality.
