Comment on: 'Universal relation between spectroscopic constants'

摘要

Kaur and Mahajan have claimed to derive a universal relation ln G = 1.91578(±0.09727) + 0.97111(±0.03809) ln Δ between the Sutherland parameter Δ(= ω_er_e~2D_e) and the dimensionless parameter G(= 8ω_ex_e/B_e) for the ground as well as excited electronic states of diatomic molecules. Validity of this relation is checked and we find that the relation is not correct. Next, we checked the validity of the relation Δ = 2.2r_e for the alkali group diatomic molecules. This relation is also found not to be correct.
