Near Edge X-ray Absorption Fine Structure (NEXAFS) spectromicroscopy, resonant scattering and resonant reflectivity are specialized,
synchrotron radiation based, soft X-ray characterization tools that provide moiety-specific contrast and either real-space imaging at w30 nm
spatial resolution, or scattering signals which can be inverted to provide chemically sensitive information at an even higher spatial resolution
(<5 nm). These X-ray techniques complement other real and reciprocal space characterization tools such as various microscopies and conven-
tional electron, X-ray and neutron scattering. We provide an overview of these synchrotron based tools, describe their present state-of-the-art and
discuss a number of applications to exemplify their unique aspects.
