This is subvolume D (appearing in three parts, D1, D2, and D3) of the Landolt-Bornstein Volume II/29 "Molecular Constants Mostly from Microwave, Molecular Beam, and Sub-Doppler Laser Spectroscopy," which is planned to appear as a series A, B, C, D1, D2, D3 for the diamagnetic, and E for the paramagnetic diatomic and paramagnetic polyatomic species, respectively. Like in the preceding volumes II/24 and II/19, which have appeared in the years around 1999 and 1992, respectively, the diamagnetic substances are arranged in the manner suggested by Hill ("Hill's system," 1900), meaning an almost...

Volume II/29 "Molecular Constants Mostly from Microwave, Molecular Beam, and Sub-Doppler Laser Spectroscopy" is planned to appear as a series A, B, C and D1, D2, D3 for the diamagnetic, and E for the paramagnetic linear and polyatomic species, respectively. Like in the preceding volumes II/24 and II/19, which have appeared in the years around 1999 and 1992, respectively, the diamagnetic substances are arranged in the manner suggested by Hill ('Hill's system', 1900), meaning an almost strict alphabetical order. The ionic species are included in the alphabetical arrangement of the neutral ones...
