PlanetPhysics/Spectroscopy Topics

Spectroscopy is broadly described as a field in physics concerned with recording of spectra, ranging from gamma to X-rays, neutrons, UV, visible, NIR, IR, microwaves, radio frequency, ultrasound, acoustic waves, gravitational, etc.

This is a contributed topic on spectroscopy themes and underlying concepts and theories.
