A new functional form for representing vibrational eigenenergies of diatomic molecules. III. Application to D2 and HD ground states

Abstract
The authors apply the proposed functional form that relates vibrational energy level to quantum number to the experimental ΔE (ν + 1/2) for the ground states of D2 and HD, making use of the isotopic masses and the concept of mass‐reduced quantum numbers. (AIP)
