Quick Reference

Symbol R. A constant that occurs in the formulae for atomic spectra and is related to the binding energy between an electron and a nucleon. It is connected to other constants by the relationship R02me4c3/8h3, where μ0 is the magnetic constant, m and e are the mass and charge of an electron, c is the speed of light, and h is the Planck constant. It has the value 1.097 × 107 m−1. It is named after the Swedish physicist Johannes Robert Rydberg (1854–1919), who developed a formula for the spectrum of hydrogen.
