Vibrational temperature

Vibrational temperature is a concept in molecular physics and thermodynamics that relates to the vibrational energy levels of molecules. It is often used to understand the population of molecules in different vibrational states at a given temperature. In quantum mechanics, molecules can exist in various vibrational states, each corresponding to a specific energy level. At thermal equilibrium, the distribution of these states among a collection of molecules follows the Boltzmann distribution, which is influenced by the temperature of the system.
