| Popis: | A resonant two-photon ionization study of the jet-cooled RuC molecule has identified the ground state as a 1Σ+ state arising from the 10σ211σ25π42δ4 configuration. The 3Δi state arising from the 10σ211σ25π42δ312σ1 configuration lies very low in energy, with the 3Δ3 and 3Δ2 components lying only 76 and 850 cm−1 above the ground state, respectively. Transitions from the X 1Σ+, 3Δ3, and 3Δ2 states to the 3Π2, 3Π1, 3Φ3, 3Φ4, 1Φ3, and 1Π1 states arising from the 10σ211σ25π42δ36π1 configuration have been observed in the 12 700–18 100 cm−1 range, allowing all of these states to be placed on a common energy scale. The bond length increases as the molecule is electronically excited, from r0=1.608 A in the 2δ4, X 1Σ+ state, to 1.635 A in the 2δ312σ1, 3Δ state, to 1.66 A in the 2δ36π1, 3Π and 3Φ states, to 1.667 A in the 2δ36π1, 1Φ and 1.678 A in the 2δ36π1, 1Π state. A related decrease in vibrational frequency with electronic excitation is also observed. Hyperfine splitting is observed in the 2δ312σ1, 3Δ3 state for... |
