# Translational partition function

The translational component of the molecular partition function, $q_T$, of a molecule in a container may be described by $q_T = \frac{V}{\Lambda^3} = V\frac{(2\pi mkT)^{\frac{3}{2}}}{h^3}$, where $\Lambda=h\sqrt{\frac{\beta}{2\pi m}}$ and $\beta=\frac{1}{kT}$.
Here, $V$ is the volume of the container holding the molecule, $\Lambda$ is the thermal wavelength, $h$ is the Planck constant, $m$ is the mass of a molecule, $k$ is the Boltzmann constant and $T$ is the temperature (in Kelvin).
