Laser spectroscopy provides model-independent nuclear data of nuclear spins, moments and charge radii across long chains of isotopes. This allows the study of the evolution of nuclear observables versus particle number to probe shape deformation, configuration mixing and structural evolution effects. The collinear laser spectroscopy setup at the IGISOL facility in the Accelerator Laboratory of the University of Jyväskylä, has been used to perform measurements on palladium isotopes (Z=46) in the mass range A=98-118. Thanks to the chemically insensitive IGISOL ion-guide production method, it has been possible to reduce the existing gap in optical spectroscopy data below Z=50, created by the refractory character of these elements. Trends in the mean-square charge radii, magnetic dipole and electric quadrupole moments will be presented and compared with state of the art theoretical calculations.
