“…R u n g e , on the other h a n d , on the basis of formulas found by them, which were of a sufficiently general character and correct to a high degree of accuracy (especially those by Kayser and R u n g e ) . T h e decisive role was played here by R y d b e r g ' s study (in the introduction we have already m a d e reference to the a u t h o r s ' paper [51] where a detailed analysis of R y d b e r g ' s contribution to progress in atomic spectroscopy was given). In his fundamental w o r k of 1890 [53], R y d b e r g represented for the first time the wave n u m b e r s of the spectral lines as the difference between two terms (two spectral terms, in the m o d e r n terminology).…”

“…A very significant point is that R y d b e r g formulated the p r o g r a m for establishing a general relation between the spectral characteristics of matter and its internal structure and implemented it as a solution to the p r o b l e m of p u t t i n g the spectroscopic material into systematic order in the framework of some semi-empirical scheme, which bears, nevertheless, a quite simple and universal character (see Ref. [51], p . 149 for m o r e detail).…”

“…To u n d e r s t a n d the role of these studies by Ritz, one needs to u n d e r s t a n d the state of theoretical spectroscopy at the beginning of his scientific career (1902); Section 2 is devoted to this, and is similar to the a u t h o r s ' paper on ' R y d b e r g and the development of atomic spectroscopy' [51]. T h e main sections are 3 and 4.…”

Walter Ritz as a theoretical physicist and his research on the theory of atomic spectraM A El'yashevich, N G Kembrovskaya, L M Tomil'chik Contents 1. General characteristics of Ritz's works 435 2. The state of theoretical spectroscopy at the beginning of the 20th century 438 3. Ritz's thesis on spectral series theory and his elastic atomic model 443 4. The magnetic atomic model and the combination principle 448 5. Conclusion 454 References 454 Abstract.A n historical and methodological analysis is given of the scientific heritage of the r e m a r k a b l e Swiss theoretical physicist Walter Ritz ( 1 8 7 8 -1 9 0 9 ) on the basis of a study of his complete w o r k s edited in 1911. T h e general characteristics of R i t z ' s w o r k s -including the p a p e r s on spectroscopy, the variational m e t h o d and electrodynamics -are discussed, and his fundamental research in the theory of atomic spectra is considered in detail. T h e elastic and the magnetic atomic models, p r o p o s e d by Ritz to explain the spectral laws and based on a classical a p p r o a c h , are discussed. It is shown that the generalised Balmer and R y d b e r g formulas and the combination principle, which later b e c a m e a basis for the formulation of B o h r ' s frequency condition, were obtained by R i t z as a result of m a t h e m a t i c a l deductions from his models and were not of a semi-empirical character as is usually believed. General characteristics of Ritz's worksT h e n a m e of Walter Ritz, a Swiss scientist of the beginning of the 20th century, needs no special r e c o m m e n d a t i o n s for physicists. In spectroscopy, the n a m e of R i t z is connected primarily with the combination principle which played an i m p o r t a n t role in the construction by Niels Bohr in 1913 of the initial q u a n t u m theory of the a t o m and its spectrum.
