Structure of nickel dichloride

Anions in laser-induced plasmas

“…The values of a j were estimated from Table 5 in [58]. The ionization potential is IðCaCl 2 Þ ¼ 10:5 eV, the total dissociation (atomization) energy D 0 0 ðCaCl 2 Þ ¼ 9:23 eV [59,60]. The one-bond breaking energy, CaCl 2 !…”

Dispersed Fluorescence from the 460-nm Band System of NiCl2: Observation of a New, Low-Lying Electronic State

“…In addition the concomitant rotational, vibrational, and electronic cooling means that a limited number of energy levels are populated which helps avoid the problems associated with overlapping and unresolvable signals that occur in static cells. This approach has allowed the unambiguous assignment of the ground state of both CuCl 2 (6) and NiCl 2 (7). In the latter case the new assignment differs from that suggested by the earlier work.…”

“…However, we chose not to pump lines in this band for the present studies because of the great congestion of lines in it, as can be seen from the excitation spectrum shown in Ref. (7). In particular, the shifts between the various Cl isotopic forms are very small for this band and there is a good chance of exciting, say, both 2 to be pumped selectively, free from interference from the other chlorine isotopomers.…”

“…The fitted origin of the à state when exciting in the ⍀ ϭ 0 This splitting can be compared with an estimate obtained from ground state parameters in the rotational analysis of the 460 nm band system (7). With the same approximations as those used earlier to estimate the separations of the 3 ⌸ g and 3 ⌺ g Ϫ states from the spin-rotation parameter ␥, the first-order spin-orbit splitting in the à state can be estimated as 355 cm…”

“…The ground state of NiCl 2 has been shown to be a 3 ⌺ g Ϫ state (7,10). The upper electronic state of the 460-nm band system is a vibronic 3 ⌸ u state which arises from either a 3 ⌬ g or a 3 ⌺ g Ϫ electronic state with one quantum of the bending vibration excited.…”
