1. rydberg unit

   In spectroscopy, the Rydberg constant, symbol R ∞ {\displaystyle R_{\infty }} for heavy atoms or R H {\displaystyle R_{\text{H}}} for hydrogen, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to the electromagnetic spectra of an atom. The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later showed that its value could be calculated from more fundamental constants via his Bohr model. Before the redefinition of the SI base units in 2019, R ∞ {\displaystyle R_{\infty }} and the electron spin g-factor were the most accurately measured physical constants.The constant is expressed for either hydrogen as R H {\displaystyle R_{\text{H}}} , or at the limit of infinite nuclear mass as R ∞ {\displaystyle R_{\infty }} . In either case, the constant is used to express the limiting value of the highest wavenumber (inverse wavelength) of any photon that can be emitted from a hydrogen atom, or, alternatively, the wavenumber of the lowest-energy photon capable of ionizing a hydrogen atom from its ground state. The hydrogen spectral series can be expressed simply in terms of the Rydberg constant for hydrogen R H {\displaystyle R_{\text{H}}} and the Rydberg formula. In atomic physics, Rydberg unit of energy, symbol Ry, corresponds to the energy of the photon whose wavenumber is the Rydberg constant, i.e. the ionization energy of the hydrogen atom in a simplified Bohr model.

1. rydberg unit

   A Rydberg unit is a unit of energy used in atomic physics, particular in the study of atomic spectra. Named after the Swedish physicist Johannes Rydberg, it is equal to the energy of a photon whose wave number is the Rydberg constant. This energy is approximately 13.6 electron volts (eV).
