Calculations on π<i>unp</i> Rydberg Terms of the Nitrogen Molecule

Abstract

A more thorough calculation is made of the lowest terms in the Worley—Jenkins Rydberg series in molecular nitrogen. A complete variation of the energy is made with respect to the screening parameters in the Rydberg functions for n=3, 4 and limited variation with parameters for functions with n=5, 6, 7. In every case investigated, a stable minimum in the term energy was found. Terms with n=5, 6, 7 agree with experimental terms to about 10%, and differences appear to decrease slightly with increasing n. Some variation was made in parameters of the core function and the effect of this limited variation on the Rydberg terms is discussed. A brief discussion is made of results on computed Rydberg defects.
