Birge-Sponer extrapolation
Birge-Sponer extrapolation [SPECT] A method of calculating the dissociation limit of
a diatomic molecule when the convergence limit cannot be observed directly, based
on the assumption that vibrational energy levels converge to a limit for a finite value
of the vibrational quantum number. { ¦bir gə spo¯ n ər ik strap ə la¯ shən }
