“…The 1 2 Π state is unbound but has a potential barrier at the avoided crossing point. The minimum for the 2 2 Π state lies at R = 1.95 Å, which is caused by the avoided crossing phenomenon between 2 2 Π and 1 2 Π states. As shown in Figs.…”

“…[1] As the candidates generating chemical laser, the excited states of the halides of Cd have been extensively investigated. [2] In addition, zinc is a significant element for biological systems and synthetic organic chemistry; and also is an important kind of transition metals in the human body, which is related to nerve disease such as Alzheimer's disease. [3,4] Another motivation is to seek the potential candidate molecules for laser cooling.…”

CdF molecule, which plays an important role in a great variety of research fields, has long been subject to numerous researchers. Due to the unstable nature and heavy atom Cd containing in the CdF molecule, electronic states of the molecule have not been well studied. In this paper, high accurate ab initio calculations on the CdF molecule have been performed at the multi-reference configuration interaction level including Davidson correction (MRCI + Q). Adiabatic potential energy curves (PECs) of the 14 low-lying Λ-S states correlating with the two lowest dissociation limits Cd( 1 S g ) + F( 2 P u ) and Cd( 3 P u ) + F( 2 P u ) have been constructed. For the bound Λ-S and Ω states, the dominant electronic configurations and spectroscopic constants are obtained，and the calculated spectroscopic constants of bound states are consistent with previous experimental results. The dipole moments (DMs) of 2 Σ + and 2 Π are determined, and the spin-orbit (SO) matrix elements between each pair of X 2 Σ + , 2 2 Σ + , 1 2 Π, and 2 2 Π are obtained. The results indicate that the sudden changes of DMs and SO matrix elements arise from the variation of the electronic configurations around the avoided crossing region. Moreover, the Franck-Condon factors (FCFs), the transition dipole moments (TDMs), and radiative lifetimes of low-lying states-the ground state X 2 Σ + are determined. Finally, the transitional properties of 2 2 Π-X 2 Σ + and 2 2 Σ + -X 2 Σ + are studied. Based on our computed spectroscopic information of CdF, the feasibility and challenge for laser cooling of CdF molecule are discussed.

“…Amplification in the green has vanished for 1342 nm -30 MW -cm-2 . Note also the steep slope of the smooth curve drawn through the data at the lowest UV intensity examined (1.8 MW -cm- 2 ). This also strongly suggests that the small signal gain coefficient for the green band is considerably larger than the values measured to date.…”

Absorption from the lowest-lying ion pair state of HgBr (i.e., Hg+–Br−: B 2∑+1/2 ) has been observed by transient absorption spectroscopy in a pulsed, transverse discharge containing a mixture of Ne, N2, and HgBr2 vapor. A highly structured band peaking at ∼447 nm is shown to be associated with charge–transfer transitions from the B 2∑+1/2 state to a higher-lying, covalently bonded (Hg*–Br) state. By pumping the 447 nm transition with a pulsed dye laser while simultaneously monitoring gain on the HgBr (B 2∑+1/2 →X 2∑+1/2 ) band at 502 nm, the absorption cross section for the blue band was measured to be (3.0±1.5)×10−17 cm2 and the saturation intensity for the transition at 447 nm was determined to be 710±50 kW cm−2.
