This title includes a number of Open Access chapters.

Spectroscopy is a powerful technique that utilizes the interaction of light with matter. Analysis of various spectra can yield important physical characteristics of matter, including chemical composition, temperature, luminosity, mass, and more. The uses and implications of spectroscopy are very broad, with practical uses in many fields of science, including astronomy, medicine, analytic chemistry, material science, geology, and more. Researchers are constantly discovering new applications of spectroscopy, and it is expected to play an ever-increasing role in nanotechnology and superconductivity. This book brings together a diverse collection of new research advances in spectroscopy.
