| 单词 | Rydberg constant |
| 释义 | Rydberg constant 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 R = µ02me4c3/8h3 , where µ0 is the magnetic constant (see permeability), 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 |
