Blue-green bands of LiCd

Spectral simulation and interpretation of LiZn and LiCd blue-green emission

“…Recently we reported the first observation of blue-green bands of LiZn and LiCd molecules produced by a photochemical reaction of excited Li2(CaH,) molecules with ground state zinc and cadmium atoms respectively [1], [2]. Analogous LiHg bands have been observed by the groups in Pisa and Graz [3].…”

“…The experimentally observed blue-green spectrum of the LiCd molecules has been identified as the result of 217 __+ v2x-, ÷ **~/2.3/2 a ~'~/a transitions [2]. A correct interpretation of the experimentally observed spectrum would require the use of LiCd potential curves from relativistic ab initio calculations which include spin-orbit interaction.…”

“…where v is the wavenumber of the transition, v = (Ev, s,-Ev,, s., )/hc, g is the degeneracy factor given by g = (2-50,A, +A')/(2--50, A,), (2) where A is the projection of the electronic orbital angular momentum on the internuclear axis, i.e. A = 0 for 27 states and A = 1 for H states.…”

“…1), A2 is the experimental fwhm (full width of the half maximum). Using the formulae (1), (2), (3) and (4) …”

Spectroscopic properties of diatomic molecules CdI and CsCd: ab initio calculations

“…To our knowledge, there is no experimental/theoretical study on the CsCd system. Several experimental and theoretical studies on similar alkali metal-zinc group metal diatomics have been published in the past focusing on the possible excimers formed from these elements [24][25][26][27][28][29][30]. Buck, Kick and Pauly performed crossed-molecular beam studies on Na-Hg [24], K-Hg and Cs-Hg systems [25] and determined intermolecular potential for these pairs.…”
