Polarisation labelling spectroscopy technique was employed to study the 3$^{1}\Pi_{u}$ state of Cs$_2$ molecule. The main equlibrium constants are $T_e=20684.60$cm$^{-1}$, $\omega_e=30.61$cm$^{-1}$ and $R_e=5.27$\r{A}. Vibrational levels $v=4-35$ were found be subject strong perturbations by neighbouring electronic states. Energies 3094 rovibronic perturbed complex determined.
In the structure of the title complex, [Cs(C7H4NO2)(H2O)2] n , the caesium salt of 4-nitro-benzoic acid, the irregular CsO9 coordination sphere comprises three bridging nitro O-atom donors, a bidentate carboxyl-ate O,O'-chelate inter-action, a triple-bridging water mol-ecule and a monodentate water mol-ecule. A three-dimensional framework polymer is generated, within which there are water-carbo...
