Rydberg Constant Value
R∞ and electron spin g-factor are the most accurately measured physical constants.
Rydberg Constant Value,R∞ 10973731.568508(65) m-1
Rydberg Constant Value,R∞ 1.097 x 107m-1
Rydberg Constant In Other Units
In atomic physics, this constant is often used and expressed in the form of Rydberg unit of energy. Thus,
Rydberg Constant in Joules 1Ry=2.178 *10-18J
Rydberg Constant in eV 1Ry=13.605693009 eV
Rydberg Constant For Elements
The value of Rydberg Constant for Hydrogen, RH 1.09677576 x 107 m1
The value of Rydberg Constant for Helium, RHe 1.09722267 x 107 m1
