Strong field ionisation dynamics have been investigated for a plethora of atomic systems and with the emergence of attosecond pulses research has been extended towards many-body systems and molecules in the high-frequency regime. Here, we want to provide a systematic study of the attosecond XUV induced single ionisation dynamics in molecules by means of solving the time-dependent Schrödinger equation of a quantum model system, comprised of two with differently bound electrons and a nucleus, numerically. This many-particle system is driven by electron-electron and nuclear-electron correlation leading to ionisation dynamics beyond the single active electron picture. We report on the impact of these correlation effects on the attosecond ionisation, as well as on the postionisation dynamics of the parent ion and reveal imprints of correlation in the photoelectron.
