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.
