Absolute numbering of asymptotic vibrational levels of diatomic molecules from cold-physics experiments
We present a simple method for determination of absolute vibrational numbering ofisolated near dissociation levels in diatomic molecules, usually observed in cold-physicsexperiments. The method is based on the isotope shift and works even when energiesof only two levels from one isotopologue and one level from another isotopologuehave been measured. It is demonstrated with data from recently reported precisemeasurements of binding energies of levels lying close to the dissociation limits inultracold Yb2, CsYb, RbSr, and RbYb molecules. Its predictions agree with those ofmuch more elaborate multi-isotope potential curve
