Show affiliationsAngle resolved two-dimensional photoelectron spectroscopy has been used to study resonances corresponding to inner-shell excitation in hydrogen halide molecules. In HBr 3d → σ* excitations have been studied, whilst in HCl and DCl 2p → σ* resonances have been explored. In HBr the photon energy positions of the two 3d5/2,3/2 → σ* resonances have been measured directly. Atomic Br is produced following dissociation of the σ* state and the asymmetric photon energy profile of Br atomic Auger lines is discussed. Angular distribution parameters of Br Auger lines have also been measured. In HCl and DCl the comprehensive nature of the analogous 2DPES reveal unexpected spectral features, the origin of which is considered.
