- Mayer f-function
-
The Mayer f-function is an auxiliary function that often appears in the series expansion of thermodynamic quantities related to classical many-particle systems.[1]
Definition
Consider a system of classical particles interacting through a pair-wise potential
where the bold labels
and
denote the continuous degrees of freedom associated with the particles, e.g.,
for spherically symmetric particles and
for rigid non-spherical particles where
denotes position and Ω the orientation parametrized e.g. by Euler angles. The Mayer f-function is then defined as
where β = (kBT) − 1 the inverse absolute temperature in units of (Temperature times the Boltzmann constant kB)-1 .
