What does the Rydberg constant represent in energy measurements?

It is a fundamental physical constant related to atomic spectral lines and corresponds to the ionization energy of a hydrogen atom in an idealized approximation.

Why convert Rydberg constant to calorie (th)?

This conversion helps relate atomic energy transitions to historical thermochemical units used in heat and specific heat capacity measurements.

Is calorie (th) still commonly used today?

No, calorie (th) is a historical unit mostly replaced by the joule, which is the preferred SI unit for energy.
