摘要
We present experimentally derived potential curves and spin-orbit interaction functions for the strongly perturbed A (1)Sigma(+)(u) and b (3)Pi(u) states of the cesium dimer. The results are based on data from several sources. Laser-induced fluorescence Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire Aim'e Cotton primarily to study the X (1)Sigma(+)(g) state. More recent work at Tsinghua University provides information from moderate resolution spectroscopy on the lowest levels of the b (3)Pi(+/-)(0u) state as well as additional high-resolution data. From Innsbruck University, we have precision data obtained with cold Cs-2 molecules. Recent data from Temple University was obtained using the optical-optical double resonance polarization spectroscopy technique, and finally, a group at the University of Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used analytic potentials (the expanded Morse oscillator form) with both finite-difference (FD) coupled-channel and discrete variable representation (DVR) calculations of the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained and compared with ab initio results from Temple and Moscow State universities.
