A review of the first x-ray excited photoelectron spectroscopical experiments will be given. The chemical shift of core levels will be discussed with the vast fields of application. From these pioneering experiments an overview of the current research concerning the chemical shift of core electrons in molecules and in free clusters will be given. A special focus will be on the different effects that have to be disentagled in order to determine chemical shifts with ultra-high precision: Core hole dynamics, molecular field splitting and more subtle correlation effects.
