Vibrational temperature

From Wikipedia, the free encyclopedia

The vibrational temperature is commonly used in thermodynamics, to simplify certain equations. It has units of temperature and is defined as

where is the Boltzmann constant, is the speed of light, and (Greek letter nu) is the characteristic frequency of the oscillator.

The vibrational temperature is used commonly when finding the vibrational partition function.
