title: Vibrational constants and binding energies for the low-lying electronic states of Sr+ CO2 from photodissociation spectroscopy.
abstract: By use of photodissociation spectroscopy of mass-selected ions, vibrationally resolved electronic spectra of the Sr+ CO2 complex are recorded in two energy regions, 20,780-22,990 and 16,210-17,550 cm(-1), correlating to the Sr+ 5(2)P <-- 5(2)S and 4(2)D <-- 5(2)S transitions, respectively. The spectra are analyzed to obtain the vibrational constants and dissociation energies of the molecular states. The observed spin-orbit splitting indicates a linear complex in agreement with theoretical calculations. The results are compared with similar systems and explained in the framework of electrostatic interactions.
