Ritz combination rule

1. Ritz combination rule The Rydberg-Ritz combination principle helps in estimating the photon energy changes during an electron transition. A Swiss physicist Walther Ritz resolved the relationship between the spectral lines of the atom in terms of their frequencies in 1908 and named it as Rydberg-Ritz combination theory. Frequency rule Wavenumber rule The principle states that the frequency of mysterious unknown spectral emission of an atom is nothing but the sum or difference of frequencies of its closely related known spectral emission lines. The principle states that the wavenumber of the unknown spectral lines of any element can be obtained by adding or subtracting the wavenumbers of the nearby spectral lines of the same element. Practical significance In simple terms, the difference in wavenumbers of hydrogen alpha and beta lines determines the Paschen -alpha line wavenumber of the hydrogen spectrum. Therefore, it is still applied today to identify the new transition lines of the atoms. Use of Ritz principle The Rydberg-Ritz combination principle deals with the identification of unknown spectral lines of the atomic spectrum. Besides, spectral studies have much significance in the analysis of the composition of astronomical matter. In particular, astronomers use this spectroscopic data to determine the constituents of stars and interstellar matter. THANK YOU THANK YOU THANK YOU Blog: https://jayamchemistrylearners.blogspot.com/
