Unformatted text preview: CHEM 350 Lectures 13, 14, and 15 February 1, 3, and 5 2010 Statistical Description of a System of Particles. Microscopic arrangements of particles : • called configuration , complexion , state (QM) • for an isolated system, each quantum state is associated with an energy level • two or more quantum states having the same energy are said to be degenerate Specification of possible quantum states of a system : • In principle : – list values of all relevant quantum numbers a very large number! a completely precise description would need to account for ALL interactions, giving the EXACT quantum states of the system. Note, however, that were the system to be found in one of these exact quantum states, it would remain there forever! • In practice : no system is ever so isolated that it can be found in one of its exact quantum states – we never know the exact microscopic state of a system of interacting particles – we therefore employ APPROXIMATE STATES by taking into account all the important...
