Statistical mechanics of classical liquids

The denominator in Eq. (5.2) is related to the classical canonical partition function. Using Eq. (5.1) this distribution function can be written as a product of 

Quantum mechanics implies the uncertainty restriction on the determination of positions and momenta, limiting the number of possible quantum states. This leads to the canonical partition function for a system of. V identical particles Q = (A I/z iVpl y
