Spectroscopy

What does it do to the atom/molecule? Types of Spectroscopy Type of radiation What does it do to the atom/molecule? What does it tell us? Name of spectroscopy X ray removes core electrons how tightly electrons are held by the nucleus; element identity Photoelectron (PES) UV-visible excites valence electrons identity or concentration of molecule or element infrared changes vibration in the bonds type of bond, atoms, or functional groups within a molecule IR (vibrational) microwave changes the rotation of atoms in the bonds location of hydrogen atoms with a molecule microwave (rotational) high energy electrons ionizes substance and sorts ions based on mass to charge ratio molecular mass of atoms or molecules mass
