Applications of synchrotron radiation in physics, chemistry, materials science, and biology has now matured from an exotic experimental field into a well-established area of science. The spectroscopy of molecules and molecular adsorbates on surfaces is one area of science, where, in the past, synchrotron-radiation-related studies had made an impact on understanding the ground-state properties as well as the dynamics. With the new high-brightness synchrotron-radiation sources ahead, this will certainly continue to be a field of very active research. This quasi-monograph reviews the current state of the field for both, the active research scientist, and the new graduate student wishing to become acquainted with this field of research.

The United States Geological Survey (USGS) is a scientific organization created in 1879, and is part of the U.S. government. Their scientists explore our environment and ecosystems, to determine the natural dangers we are facing. The agency has over 10,000 employees that collect, monitor, and analyze data so that they have a better understanding of our problems. The USGS is dedicated to provide reliable, investigated information to enhance and protect our quality of life. This is one of their circulars.
