We know that he had found his results by September since he wrote to the Royal Swedish Academy of Sciences at this time requesting financial support and attached to his application an appendix listing the results he later announced publicly.

Preliminary Notice Communicated by the Author which was published in In this preliminary notice, he stated that his researches had been only on elements in groups I, II, and III of the periodic table. However, he was certain that the laws he had found applied to all elements. It also was published by the Academy in We now look at some of Rydberg's comments in these papers.

He had been led to study spectral lines of elements because of the work of Dmitri Ivanovich Mendeleyev - who had produced his periodic table of the elements in Mendeleyev's work was, at first, greeted with little enthusiasm but this changed over the years. Rydberg writes in Recherches :- With the discovery by Mendeleyev of the periodic table of elements, there has arisen a new point of departure of great importance for all the work which I study here.

However, it has been used but little. In 'Om de kemiska' I have concluded that the periodicity of a great number of physical coefficients must depend on the fact that the force which acts between two atoms of the same, or of different elements, is a periodic function of the atomic weight. He states that, except for the Balmer formula for the spectrum of the hydrogen atom, the He gives a formula based on various constants and johanneses rydberg contributions to mineralogy that Therefore, if the spectra of two elements in the periodic table are known, the spectrum of the element in between them can be calculated using interpolation.

He continued to study the problem of spectral lines and in his paper Lines in the Hydrogen Spectrum he writes:- As I have pointed out already in my general exposition of the constitution of line spectra, and have afterwards tried further to confirm, there can be no doubt that these series are really parts of a single group of lines with two variable integral parameters, the general formula of which can be written approximately.

He hoped to determine the structure of the atom but, although his work did provide the basis for the structure theory, he himself did not reach his goal. Only after Ernest Rutherford had proposed his model of the atom, and Niels Bohr and Max Planck had added a quantum theory approach to the theory of atomic structure, was the foundation in place to give a correct theoretical account of spectral data.

We have seen above that Rydberg only became a full professor in He was 54 years old, but sadly his health soon began to deteriorate. He had a stroke in and, although he recovered sufficiently to return to work, he began to suffer heart and circulation problems. His health continued to deteriorate and he became seriously ill in Although he continued to hold the chair he took sick leave in and was absent from the university from that time on.
