Reciprocal Centimeters To Electronvolts per Photon Converter
Reverse Conversion
How This Converter Works
Convert between Reciprocal Centimeters (cm⁻¹) and Electronvolts per Photon (eV/photon). Select either direction to convert directly.
Formula or rule
Electronvolts per Photon = Reciprocal Centimeters * 0.0001239841984332; Reciprocal Centimeters = Electronvolts per Photon / 0.0001239841984332
Example
- Input
- 1 cm⁻¹
- Calculation
- 1 * 0.0001239841984332 = 0.0001239841984332
- Result
- 0.0001239841984332 eV/photon
Notes
Spectroscopic wavenumber is reciprocal wavelength, conventionally expressed in cm⁻¹. The frequency and photon-energy equivalents here assume vacuum propagation and use ν = cṽ and E = hcṽ with exact SI values of c, h, and the elementary charge.
