For the New Century issue of Theoretical Chemistry Accounts, we asked the advisory editors of the journal to identify a paper from the first century of theoretical chemistry and discuss its importance for the twentieth century with an eye towards the twenty-first century. Although we collected 66 such perspectives, they are far from representing a full set of the papers deserving our reflection. At one point we thought of inviting additional perspectives to fill some obvious gaps or provide better balance, but we decided that any such attempt would spoil the spontaneity of the collection, which is part of its interest. We hope the Theoretical Chemistry Accounts New Century Issue will be entertaining, but even more we hope it will help younger scientists to see the role that selected creative efforts of the past have played in getting us to the pres ent. Further, to the extent that this issue inspires members of the theoretical chemistry community to reread the papers that led to the present state of the art, that is all to the good, because there is still a lot to be learned from the last century's literature. Finally, taking this issue as prolog, we can all try to make our upcoming efforts as influen tial for the next century as these papers were for the last. C. J. Cramer, D. G.

The separation of kinematical relativistic effects attributed the fine structure of atomic spectra to and fine-structure splitting is discussed considering the relativistic effects, and thus published the first paper spherical orbits. giving a quantitative perspective on relativistic quantum In the third section, X-ray spectra (Röntgenspektren) chemistry. of the hydrogen atom are discussed.

The paper is characterized by a Sommerfeld transformation quick adaptation and rapid development of the ideas of the "old quantum theory" introduced by Bohr, which was vividly discussed in the contemporary Iiterature [2--4]. The simultaneaus treatment of relativity and quantum effects is the first of its kind.

These quantization rules for integr phase integrals, enabling the application of the "old able systems were later refined by Keller [6] and are quantum theory" to nonspherical orbits, is introduced in known as Einstein-Brillouin-Keller rules. The method this section. Sommerfeld uses these new rules to derive of semiclassical quantization was revived in the early the expressions for the elliptic (bound-state) orbits, in 1980s, when Gutzwiller [7] found a way to apply particular the ones with nonspherical symmetry, i.e., semiclassical quantization also to nonintegrable systems. nonvanishing eccentricity, e.
