We have studied single photon double K-shell ionization of small molecules (N2, CO, C2H2n (n = 1-3), . . .) and the Auger decay of the resulting double core hole (DCH) molecular ions thanks to multi-electron coincidence spectroscopy using a magnetic bottle time-of-.ight spectrometer. The relative cross-sections for single-site (K-2) and two-site (K-1K-1) double K-shell ionization with respect to single K-shell (K-1) ionization have been measured that gives important information on the mechanisms of single photon double ionization. The spectroscopy of two-site (K-1K-1) DCH states in the C2H2n (n = 1-3) series shows important chemical shifts due to a strong dependence on the C-C bond length. In addition, the complete cascade Auger decay following single site (K-2) ionization has been obtained.
