    2. Spectroscopy for the Unpolarized
      • What is Spectroscopy?
      • Why are spectra taken and recorded?
      • Spectra Types Electromagnetic, Mass Spectrometry
      • Primary Spectra types
        • Sample spectra and features
        • Creation of spectra

    3. What is Spectroscopy?
      • Spectroscopy is the study of the interaction between radiation and matter.
      • Spectrometry is the measurement of these interactions.
      • An instrument which performs the measurements is a spectrometer or spectrograph .
      • A plot or graph is referred to as a spectrogram or spectrum .
    4. Why are Spectra taken and recorded?
      • Observe how substances behave at certain energy levels
      • Serve as identification tools for a chemical substance
      • Help predict behavior of unknown substances or newly synthesized materials from ones already characterized
    5. Types of Spectroscopy
      • Electromagnetic spectroscopy - interactions with electromagnetic radiation, or light. (UV, Visible, IR, X-Ray)
      • Mass spectroscopy (Mass Spectrometry) - interaction of charged species with a magnetic field, giving rise to a mass spectrum.
      • Nuclear Magnetic Resonance (NMR)
      • Less common in the literature:
      • Electronic spectroscopy - electrons
      • Mechanical spectroscopy – macroscopic effects (vibrations, acoustics, etc.)

      • Ask patron or identify a similar substance as a reference
    25. Search Strategies (2)
      • Search acronyms as well as full spellings of spectra types to find literature sources
      • Journal articles with spectra frequently have
        • different types of spectra for one chemical substance
        • Same spectra for a group of related substances
      • Preparation papers are more likely to have spectra
