Experimental investigation of the Cs2 a Σ3u+ triplet ground state: Multiparameter Morse long range potential analysis and molecular constants

Abstract

We have observed the vibrational levels v(") = 0-40 of the Cs(2) a (3)Sigma(u)(+) state by perturbation facilitated infrared-infrared double resonance excitation and spectrally resolved fluorescence measurements, and derived a multiparameter Morse long range potential and molecular constants based on these data.
