SUMMARY
The discussion clarifies that cm-1 is not a unit of energy but rather a unit of wavenumber, which relates to the energy of photons. The conversion to energy units such as ergs or joules involves understanding the energy of a photon with a specific wavelength. For instance, a photon with a wavelength of 1 cm corresponds to an energy of approximately 1.99 x 10-23 Joules, derived from the formula 100 h c. The context of this conversion is particularly relevant in chemistry, especially in problems related to crystal fields.
