Solved Examples. Example 1. According to Paschen series, n 1 = 3 and n 2 = 4, 5 Therefore, the second line in the Paschen series is set by putting n 1 = 3 and n 2 = 5 . Rydberg's phenomenological equation is as follows: (1.5.1) ν ~ = 1 λ (1.5.2) = R H ( 1 n 1 2 − 1 n 2 2) where R H is the Rydberg constant and is equal to 109,737 cm -1 and n 1 and n 2 are integers (whole numbers) with n 2 > n 1. For the Balmer lines, n 1 = 2 and n 2 can be any whole number between 3 and infinity.

The value of R H that we used in the text, and are instructed to calculate in this experiment, is equal to about 2.178 x 10-18 J. This R H represents the product of Planck's constant (h) which is 6.626x10-34 J·s, and the actual Rydberg constant (3.28984 x 10 15 s-1). Rydberg constant definition is - a wave number characteristic of the atomic spectrum of each element equal to the constant factor in the wave-number formula for all the spectral series of the elements and having a value from 109,678 cm—1 for hydrogen to 109,737 cm—1 for the heaviest elements. The Rydberg constant differs somewhat for different elements, and the value usually given is that calculated for an atom of infinite nuclear mass. The best current value is 10 973 731.568 527 ± 0.000 073 per meter ( 2006 CODATA value)¹. Rydberg constant and the other fundamental physical constants. We review the five recent precision mea- surements [2-61 that have advanced the accuracy of the Rydberg constant beyond 1 part in lo’. Finally, we discuss the limitations of these recent measurements and the future of Rydberg-constant determinations.

Multiply the constant in Hz by Planck's constant to get its value in Joules. Rydberg Constant. Rydberg constant is a physical constant named after Swedish physicist Johannes Rydberg. The constant relates atomic spectra, in the science of spectroscopy and is denoted by the symbol R ∞. It is the constant for heavy atoms or R H for hydrogen.

Using a cryogenic beam of H atoms, we measured the 2S-4P transition frequency in H, yielding the values of the Rydberg constant R ∞ = 10973731.568076(96) per meter and r p = 0.8335(95) femtometer. Our r p value is 3.3 combined standard deviations smaller than the previous H world data, but in good agreement with the µp value. Here, n is any integer greater than 2 and R is defined as Rydberg constant and its value is equal to 1.097 × 1 0 7 m − 1 1.097{\text{ }} \times {\text{ }}{10^7}{m^{ - 1}} 1.
