Abstract
The linear correlations of Rydberg energy versus ionization potential [S. Chattopadhyay, P. Hochmann, and S. P. McGlynn, J. Chem. Phys. 65, 3341 (1976)] for p6, s2, and d10s2 atoms are extended to open-shell s1, p5, p4, and p3 systems. The intercepts lead to the concept of an ’’average (or zero-order) member of a group’’. The slopes exhibit a 1/(n̄*)2 dependency, where n̄* is the average effective quantum number. This fact establishes a connection with the quantum defect approach. The molecular Rydberg correlations [P. Hochmann, P. H. Templet, H.-t. Wang, and S. P. McGlynn, J. Chem. Phys. 62, 2588(1975)] are extended to different molecular groups. The standard deviations are seldom larger than 1000 cm−1 and often less than 100 cm−1. It is concluded that these correlations constitute a potent assignment device.
