The experimentally determined eletronic energy levels of approximately 500 neutral and ionic transient molecules possessing from 3 to 6 atoms are tabulated together with the associated vibrational structure, the radiative lifetime, the principal rotational constants, and references to the pertinent literature. Vibrational and molecular beams, and in rare-gas and nitrogen matrices are included. The types of measurement surveyed include conventional and laser- based absorption and emission techniques, laser absorption with mass analysis, and ultraviolet photoelectron spectroscopy.
