Ionization and excitation energies for the Rydberg states (3,1B1, 3,1A2, 3,1A1 lying above the ground state 1A1) of the water molecule have been calculated via the multiple-scattering X a (MSX a) method. Both singlet and triplet states have been computed self-consistently. The first ionization energy of the molecule was also computed.

Abstract Ab initio frozen core CEPA calculations have been performed in order to predict vertical energy levels and disccosiation energies for the Rydberg states of H 4 up to n eff = 5. The electron correlation energies are analysed and discussed.

Abstract The absorption spectrum of CCI has been observed on SUPERACO in Orsay (France) in a microwave discharge in He + CCl 4 down to 1050 A. The B 2 Σ + state observed by Melen et al. ( J. Phys. B: Atom. Mol. Phys. 16, 2523-2530 (1983)) has been confirmed. Nineteen states have been classified into five Rydberg series converging to 9.051 ± 0.

A basis set of atomic orbitals that is very close to atomic Rydberg orbitals is used to calculate the Rydberg levels in diatomic CH. Good agreement is found with the experimental assignments, and bands at 81 006, 81 545, and 82 788 cm−1 are attributed to an nf series. An explanation is suggested for only two members of the np series being observed.

While Rydberg atoms have been extensively studied for well over a decade, high resolution laser studies of Rydberg molecules have only recently begun. To the extent that an electron moves far from the core, one might expect that Rydberg molecules should differ little from Rydberg atoms.

Abstract The absorption spectrum of S 2 has been observed down to 400 A on the SA63 line of SUPERACO (LURE) in Orsay, France. Two already reported Rydberg Series converging to the X 2 Π g ground state of S + 2 , π 4 u π 2 g X 3 Σ − g → π 4 u π g (π u np ) 3 Σ − u and π 4 u π 2 g X 3 Σ − g → π 4 u π g (σ

Abstract The absorption spectrum of PN has been observed after the pyrolysis of P 3 N 5 by using the synchrotron radiation of SUPERACO in Orsay (France). Sixteen new states have been observed up to 1050 A and classified into five Rydberg series ( nsσ , npπ , npσ , ndπ , ndσ ) converging to 11.83 ± 0.02 eV, in perfect agreement with the ...

AbstractThe excited states of molecules can be divided into three categories: valence‐shell, Rydberg, and intermediate. Reasons are given why this classification is important for photochemistry. The photolytic primary steps should be different for excited states falling into these different categories.

Herzberg6 has recently observed very highly excited states of H3 in the emission from a hollow cathode discharge through H2. The emission bands were assigned to Rydberg transitions. Calculations are reported to interpret these transitions. (AIP)

High Rydberg states of helium hydride
Physical Review A, 1989High-lying Rydberg states (11\ensuremath{\le}n\ensuremath{\le}34) of helium hydride have been observed. They were produced by laser excitation of a fast molecular beam and detected by field ionization. Ionization potentials, quantum defects, and the binding energy of ${\mathrm{HeH}}^{+}$ were determined.
