| Popis: | The E 1 Σ + `Rydberg' state of 24 Mg 16 O has been characterized by two-color resonance-enhanced two-photon ionization (R2PI) spectroscopy in the 36 000–40 000 cm −1 region. Several rotationally resolved bands, assigned consistently to 24 Mg 16 O( E 1 Σ + ← X 1 Σ + ) vibronic transitions, have been analyzed. The effective B v ′ ( v ′ =0−8) constants determined exhibit an unusual variation with v ′ . Possible causes of this variation are discussed. Estimated spectroscopic constants for the E 1 Σ + state are reported. |
