title: Surface aligned reaction.
abstract: This paper reflects on three decades during which the study of surface aligned reaction (SAR) has advanced. The objective in SAR, which in considerable part still lies ahead, is the simultaneous control of atomic and molecular "collision energies, collision angles, and impact parameter." Following a discussion of the benefits of such an approach we review the progress made, and, as a stimulus to experiment, present new calculations of SAR dynamics for bimolecular reaction at a metal surface. It seems reasonable to suppose that we are now entering a decade in which a combination of scanning tunneling microscopy and femtosecond laser spectroscopy will bring the full realisation of SAR.
