• Atoms are thermally excited so that they emit light and the radiation emitted is measured?

  Atomic Emission Spectrophotometry
• Atoms of a metal are volatilized in a flame and their absorption of a narrow band of radiation

  produced by a hollow cathode lamp, coated with the particular metal being determined, is measured?

  Atomic Absorption Spectrophotometry
• Certain molecules, particularly those with a chromophore and a rigid structure, can be excited

  by UV/visible radiation, and will then emit the radiation absorbed at a longer wavelength. The

  radiation emitted can then be measured?

  Fluorescence Spectrophotometry
• Radiation in the radiofrequency region is used to excite atoms, like protons or carbon-13 atoms,

  so that their spins switch from being aligned with to being aligned against an applied magnetic

  field?

  Nuclear Magnetic Resonance Spectroscopy
• Charged molecules or molecular fragments are generated in a high-vacuum region, or

  immediately prior to a sample entering a high-vacuum region, using a variety of methods for

  ion production?
