| Abstract: | Starting from the spectroscopic constants, an electronic potential for the ground state hydrogen molecule is presented. Self-consistence is checked by numerical integration of the radial wave equation. The mean eigenvalue deviation is about 1 cm−1. Comparison with the latest theoretical work is considered. New revised spectroscopic constants and vibrational quanta are calculated. |
