Given: The units of cm⁻¹ and Joules
To find: Conversion between cm⁻¹ and Joules
Solution: The reciprocal length is used as a measure of energy like cm,m, mass, frequency, etc.
According to the Plank-Einstein relation, the frequency of photon yields photon energy, and this frequency is related to a spatial frequency which is a reciprocal unit.
Therefore, cm⁻¹ is an energy unit = energy of a photon with a wavelength of 1cm.
The energy of photon = 1.986 x 10⁻²³ J
Energy is inversely proportional to the size of the unit
Therefore, 1 cm⁻¹ = 1.986 x 10⁻²³ J
Hence, 1 cm⁻¹ = 1.986 x 10⁻²³ J
