In the last two decades, surface-science experiments and techniques have been developed to focus on obtaining molecular information under reaction conditions at high pressures (near or above 1 bar) and liquid interfaces to monitor catalysts and biointerfaces.  This presentation will describe the results of these studies obtained by surface-sensitive laser spectroscopies, scanning tunneling microscopy, and X-ray spectroscopies usually practiced at a synchrotron light source.  The use of model surfaces, single crystals and monodisperse nanoparticles with variable size (1-10 nm) and shape facilitates meaningful interpretation of the experimental data.  These methods allow evaluation of the molecular structures of intermediates, oxidation states of metals, and mobility of adsorbates.  New techniques that are likely to make major contributions to the investigation of surfaces under reaction conditions are also discussed.
