      abstract     = {The determination of reaction pathways and the
                      identification of reaction intermediates are key issues in
                      chemistry. Surface reactions are particularly challenging,
                      since many methods of analytical chemistry are inapplicable
                      at surfaces. Recently, atomic force microscopy has been
                      employed to identify surface reaction intermediates. While
                      providing an excellent insight into the molecular backbone
                      structure, atomic force microscopy is less conclusive about
                      the molecular periphery, where adsorbates tend to react with
                      the substrate. Here we show that photoemission tomography is
                      extremely sensitive to the character of the frontier
                      orbitals. Specifically, hydrogen abstraction at the
                      molecular periphery is easily detected, and the precise
                      nature of the reaction intermediates can be determined. This
                      is illustrated with the thermally induced reaction of
                      dibromo-bianthracene to graphene which is shown to proceed
                      via a fully hydrogenated bisanthene intermediate. We
                      anticipate that photoemission tomography will become a
                      powerful companion to other techniques in the study of
                      surface reaction pathways.},
