“…The HeICl complexes were prepared and stabilized in a supersonic jet expansion with a pulse duration of about 200 μs like that described elsewhere (see Refs. [16–27] and references). The helium with typical backing pressure of p He =30 atm passed through the bubbler packed with mixed ICl crystals and a polytetrafluoroethylene facing cooled down to ∼10 °C.…”

The article presents results of experimental and theoretical analysis of the T‐shaped and linear HeICl van der Waals complexes in the valence A1 and ion‐pair β1 states as well as the HeICl(A1,vA,nA←X0+,vX=0,nx and β1,vβ,nβ←A1,vA,nA) optical transitions (ni are quantum numbers of the vdW) modes). The HeICl(β1,vβ,nβ)→He+ICl(E0+, , β1) decay are also studied. Luminescence spectra of the HeICl(β1,vβ=0–3,nβ) complex electronic (ICl(E0+,vE, ) and vibrational ICl(β1,vβ) predissociation products are measured, and branching ratios of decay channels are determined. To construct potential energy surfaces for the HeICl(A1, β1) states, we utilized the intermolecular diatomic‐in‐molecule perturbation theory first order method. Experimental and calculated spectroscopic characteristics of the A1 and β1 states agree well. Comparison of the experimental and calculated pump‐probe, action and excitation spectra shows that the calculated spectra describe the experimental spectra adequately.

“…Interpretation of the present spectral results should benefit from the extensive work on the spectroscopy of I 2 [26][27][28][29][30][31][32], as well as of the other relevant species [25,[33][34][35][36][37][38]. There are, nevertheless, recent experiments aimed at further elucidating the electronic structure of iodine which suggests that iodine remains a molecule of considerable interest [39][40][41][42]. Molecular iodine also continues to be an important benchmark in theory [43][44][45], including that of electron-molecule collisions [46,47].…”

We have determined absolute apparent excitation cross sections for photoemission in the 300–1050 nm spectral region resulting from collisions of I2 with electrons of 4.8–100 eV translational energy. Experiments were done in single collision conditions and emission is observed from I2, I2 +, I and I+. All the emission features appear to turn on at the energy thresholds for formation of the respective excited state species. At higher electron beam energy the spectra are dominated by emissions from the strong I2 + A–X band, as well as the intense emission from several I 5s 25p 46s states. An attempt to determine the initial I2 + A populations generated from electron impact is discussed. These populations are determined from simulations of the I2 + A–X emission band using both experimentally and theoretically determined potential energy surfaces available in the literature. Direct, vertical formation of I2 + A from I2 X is only supported in the case of the ab initio potential energy surface.
