Molecular Constants Mostly from Microwave, Molecular Beam, and Sub-Doppler Laser Spectroscopy Paramagnetic Diatomic Molecules (Radicals), Part 1

High-resolution spectroscopic data of paramagnetic diatomic molecules are presented in data sheets. All relevant properties of a molecule and the corresponding parameters can be found concentrated under its sum formula: rotational and related constants, the dipole moments, barriers to internal rotation, hyperfine coupling parameters, or Zeeman data.
