    After completing this unit the student will be able to:

    • Describe the selection rule for infrared-active transitions.
    • Determine the vibrations for a triatomic molecule and identify whether they are infrared-active.
    • Draw the design of a non-dispersive infrared spectrophotometer and describe how it functions.
    • Describe the difference between time and frequency domain spectra.
    • Explain how a Michelson Interferometer can be used to obtain a time domain spectrum.
    • Explain the advantages of Fourier Transform infrared spectroscopy over conventional infrared spectroscopy.
