Molecular Spectra and Molecular Structure IV. Constants of Diatomic Molecules  Molecular Spectra and Molecular Structure IV. Constants of Diatomic Molecules, by K. P. Huber and Gerhard Herzberg (Van nostrand Reinhold company, New York, 1979, ), is a classic comprehensive multidisciplinary reference text contains a critical compilation of available data for all diatomic molecules and ions known at the time of publication - over 900 diatomic species in all - including electronic energies, vibrational and rotational constants, and observed transitions. Extensive footnotes discuss the reliability of these data and additional detailed informationon potential energy curves, spin-coupling constants, /\-type doubling, perturbations between electronic states, hyperfine structure, rotational g factors, dipole moments, radiative lifetimes, oscillator strengths, dissociation energies and ionization potentials when available, and other aspects. Herzberg received the 1971 Nobel Prize in Chemistry; both authors are world-renowned highly respected scientists.
