The Rydberg constant and proton size from atomic hydrogen Si28kg01b, was measured only at PTB and yielded nearly the same Avogadro constant value.

Rydbergs formel i ett protokoll från 5 november 1888 Rydbergs formel upptäcktes 1888 av fysikern Janne Rydberg för att beräkna spektrallinjer från atomer. Han hade upptäckt en regelbundenhet i vågtalen av spektralserier som kunde skrivas som där λ är det utstrålade ljusets våglängd, m och n är heltal sådana att m > n och

Empirical formula discovered by Balmer to describe the hydrogen spectra 1 where n are integers, 3, 4, 5, … up to infinity and R is a constant now called the Rydberg constant. In the SI system of units, R=1.097 x 107 m-1. Balmer suggested that his formula may be more general and could describe spectra from other elements. Then in 1889, Johannes Robert Rydberg found several series of spectra that would fit a more It turns out that there are families of spectra following Rydberg's pattern, notably in the alkali metals, sodium, potassium, etc., but not with the precision the hydrogen atom lines fit the Balmer formula, and low values of \(n_2\) predicted wavelengths that deviate considerably. Rydberg's phenomenological equation is as follows: Rydberg constant † Numerical value: 10 973 731.568 160 m-1: Standard uncertainty: 0.000 021 m-1: Relative standard uncertainty: 1.9 x 10-12: Concise form 10 973 731.568 160(21) m-1 † The full description of unit m-1 is cycles or periods per meter.

Rydberg constant is the value of highest wavenumber(inverse of wavelength) that any photon can emit.

f. is 2, as shown in Equation (1). The reciprocal of the wavelength, 1/λ, is termed the wavenumber, as expressed by Rydberg in his version of the Balmer equation. The Rydberg Formula applicable to the spectra of the different elements and is it is expressed as. Where, n1 and n2 are integers and n2 is always greater than n1. R is constant, called Rydberg constant and formula is usually written as. The modern value of Rydberg constant is known as 109677.57 cm-1 and it is the most accurate physical constant.

The significance of the Rydberg constant was not understood in its entirety until 1913 when Neils Bohr published a paper on the structure of the atom [3]. The Rydberg constant is determined by measuring the wavelength or frequency of a spectral line of a hydrogenlike atom or ion. The highest resolution and accuracy has been achieved by the method of Doppler-free two-photon spectroscopy, which permits the observation of very sharp resonance transitions between long-living states. It turns out that there are families of spectra following Rydberg's pattern, notably in the alkali metals, sodium, potassium, etc., but not with the precision the hydrogen atom lines fit the Balmer formula, and low values of \(n_2\) predicted wavelengths that deviate considerably. The value 109677 cm − 1 is called the Rydberg constant for hydrogen. I checked online and found that in most (all) websites (incl. Wikipedia), the value of Rydberg constant is 109677 cm − 1.
