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

3. Mass Spectrometer
Higher charges bend more
Lighter particles bend more
