The optical absorption spectrum of Sr+Xe, is measured in the 21500-23300 cm-1 energy region, using photofragmentation spectroscopy of mass-selected ions. The spectrum consists of two vibrational progressions that are due to dipole transitions from the X2Σ1/2 electronic ground state to vibrational levels of the excited Α2Π1/2 and Α2Π3/2 states. From isotope-resolved measurements and using the approximation of the anharmonic oscillator, we calculated the vibrational constants for the ground X2Σ1/2 and the excited Α2Π1/2, Α2Π3/2 states. Finally, we estimate the binding energies of the involved states with the aim of an electrostatic potential model. (EN)
