RESOLVED FLUORESCENCE SPECTROSCOPY OF THE Cs_23~3Π_g→b~3Π_u TRANSITION

摘要

Perturbation facilitated Infrared-Infrared double resonance spectroscopy has been used to study the triplet states of Cs_2.The 3~3Π_g state has been observed rotationally resolved fluorescence spectra into the b~Π_u state and the perturbed A~1Σ_u~+ levels have been recorded. Molecular constants of the b~3Π__(0u)and A~1Σ_u~+ states were derived from the fluorescence spectra.
