Rydberg energy, effective

One of the first properties to be explored was the sensitivity of Rydberg atoms to external electric fields, the Stark effect. While ground state atoms are nearly immune to electric fields, relatively modest electric fields not only perturb the Rydberg energy levels, but even ionize Rydberg atoms, as was shown in early... 

The quality of the ) states has been tested through their energy and also their transition moment. Moreover from the natural orbitals and Mulliken populations analysis, we have determined the predominant electronic configuration of each ) state and its Rydberg character. Such an analysis is particularly interesting since it explains the contribution of each ) to the calculation of the static or dynamic polarizability it allows a better understanding in the case of the CO molecule the difficulty of the calculation and the wide range of published values for the parallel component while the computation of the perpendicular component is easier. In effect in the case of CO ... 

The 0(1D) + HD reaction was also studied using the same Rydberg tagging TOF technique described above. The experiment was carried out at a collision energy of 1.7kcal/mol, which is below the 1.8 kcal/mol barrier for the abstraction mechanism inferred from previous experimental studies.63 The purpose of this experimental study is to investigate the isotope effect on this reaction. 

Urey, Brickwedde, and Murphy (UBM) set out to discover isotopes of hydrogen. They knew the energy levels of the hydrogen atom and they knew the effect of the mass of the nucleus on these energy levels. The Rydberg constant depends on the... 

The same conclusion can be drawn from the results obtained for excited states of H2. As an example, in Table VI the energies for the unbounded lowest triplet b state obtained using ECG, KW, Hy-CI and conventional Cl are compared. For higher excited (Rydberg) states the difference between energies calculated using explicitly correlated functions and Cl function becomes smaller since the importance of the effect of electron correlation is decreasing.
