The HeI2(ion-pair states) van der Waals complexes

Molecular parameters for weakly bound 2g(aa,ab) and ${0}_{u}^{-}(ab)$ states of molecular iodine and dipole moment functions of transitions to these states

“…The transition on the second step occurs due to hyperfine mixing between the rovibronic levels of all three states correlating with the third dissociation limit [9,20].…”

“…It was found that the fundamental Nd:YAG laser harmonic consists of three spectral components: n f 1 = 9395.12 ± 0.02 cm −1 , n f 2 = 9393.53 ± 0.07 cm −1 and n f 3 = 9396.67 ± 0.10 cm −1 , and a very weak line with a frequency of [9,20].…”

Experimental and Theoretical Studies of the HeICl Van der Waals Complexes in the Valence and Ion‐pair States

“…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.…”

“…Luminescence of the NeICl( E , $${D{ {^\prime}}}$$ , β ) have been observed, [14] and excitation spectra of luminescence of the HeICl( E , β ) decay products have been measured [15] . Population and decay (luminescence, vibrational predissociation, VP, and electronic predissociation, EP) of the RgI 2 ( E , v E , n E ), Rg=He, Ne, Ar, Kr, N 2 I 2 ( E , v E , n E ) vdW complexes, and HeNeI 2 ( E , v E , n E ) trimer have also been studied [16–24] (hereafter n i are quantum numbers of the vdW modes).…”
