Rydberg-valence interactions of CO, and spectroscopic evidence characterizing the C[sup ʹ] [sup 1]Σ[sup +] valence state

Rydberg-valence interactions of CO, and spectroscopic evidence characterizing the C' 1Sigma+ valence state.

Rotationally cold absorption and two-photon ionization spectra of CO in the 90-100 nm region have been recorded at a resolution of 0.3-1.0 cm(-1). The analyses of up to four isotopomers seek to clarify the observations in regions where the Rydberg levels built on the ground state X (2)Sigma(+) of the ion interact with valence states of (1)Sigma(+) and (1)Pi symmetry. Previous observations of th...

Rydberg - valence interactions of CO , and spectroscopic evidence characterizing the C 8 1 S ¿ valence state

Rotationally cold absorption and two-photon ionization spectra of CO in the 90–100 nm region have been recorded at a resolution of 0.3–1.0 cm. The analyses of up to four isotopomers seek to clarify the observations in regions where the Rydberg levels built on the ground state X S of the ion interact with valence states of S and P symmetry. Previous observations of the 3ss , B S Rydberg state, r...

Relations between Rydberg-valence interactions in the O 2 molecule

On the Possibility of Mixed Rydberg-Valence Bonds

Chemical bonding between the Rydberg molecule NH4 and three alkali atoms Li, Na, and K, via their 2s, 3s, or 4s valence orbitals, is examined using flexible atomic orbital basis sets and high level ab initio methods. The results thus obtained suggest that (NH4)Na and (NH4)K should have large enough barriers to fragmentation (to (NH3) plus the alkali hydride) to be detected experimentally if it ...

Rydberg–valence interactions in CH2Cl\CH2¿Cl photodissociation: Dependence of absorption probability on ground state vibrational excitation

A strong enhancement of absorption to the lowest A1 state is observed for vibrationally excited chloromethyl radicals. It is demonstrated that this enhancement is due to a significant increase in both electronic and vibrational Franck–Condon factors. Electronic structure calculations of potential energy surfaces ~PESs! and transition dipole moments for the ground and the two lowest excited stat...
