A fluorescence spectrum, excited by the synchrotron radiation of Superaco in a microwave discharge through He + SiCl(4), leads to the observation of five new electronic states of SiCl, converging to the ground X(1)Sigma(+) state of the SiCl(+) ion. The (n s varsigma) and (n p pi) Rydberg series are extended respectively to n = 6 and n = 7.

Molecular Rydberg states. Low-energy Rydberg states of azulene
The Journal of Physical Chemistry, 1983Electronic spectra of azulenes are discussed. The low-energy Rydberg states are emphasized. The 3d-Rydberg states lie at 45,000 to 50,000 cm/sup -1/. They are partially quenched by chemical substituents and totally quenched in condensed media. The 3p-Rydberg states lie at approx. 40,000 cm/sup -1/ in azulene and are largely quenched in all derivatives.

Rydberg states of calcium fluoride
Physical Review Letters, 1993We derive the entire singly excited electronc level spectrum of a dipolar molecule (CaF) from atomic properties alone (the quantum defects of ${\mathrm{Cd}}^{+}$). In the approach presented here the motion of the lone electron is treated as a double scattering process involving the closed-shell ${\mathrm{Ca}}^{++}$ and ${\mathrm{F}}^{\mathrm ...

Abstract New uv absorption spectra have been observed for SiBr. Five Rydberg states are identified to the states (4sσ) 2 Σ + , (5sσ) 2 Σ + , (4pπ) 2 Π , (3dπ) 2 Π , and (3dδ) 2 Δ by comparison with SiF and SiCl.

The ultraviolet spectrum of butadiene is a key element in interpreting the spectra of the conjugated polyenes. The lack of a detailed study of this molecule prompted us to examine the spectra of butadiene- d₀, 2, 3-d₂, 1, 1, 4, 4-d₄, and 1, 1, 2, 3, 4, 4-d₆.

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 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 ...

CCl radical has been observed from 280 to 410 nm by resonance enhanced multiphoton ionization (REMPI) spectroscopy. Transitions from the ground state to Rydberg states are observed in the range of 40 000–70 000 cm−1, and to the previously known A 2Δ state at 36 000 cm−1.

Publisher Summary This chapter is devoted to the production and detection of Rydberg states; every experiment starts and ends with these processes. The main results of spectroscopic studies are analyzed and a strong emphasis is placed on the effects of external fields as this is probably the domain where the most interesting and sometimes surprising ...

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.
