convergence limit

[kən′vər·jəns ‚lim·ət]
(spectroscopy)
The short-wavelength limit of a set of spectral lines that obey a Rydberg series formula; equivalently, the long-wavelength limit of the continuous spectrum corresponding to ionization from or recombination to a given state.
The wavelength at which the difference between successive vibrational bands in a molecular spectrum decreases to 0.
