    1. Consider the molecular vibrations of carbon dioxide and determine whether or not they are Raman active.
    2. Which set of lines, Stokes or anti-Stokes, is weaker?
    3. What effect would raising the temperature have on the intensity of Stokes and anti-Stokes lines?
    4. What would be the ideal source to use for measuring Raman spectra?
    5. The molecule carbon tetrachloride (CCl4) has three Raman-active absorptions that occur at 218, 314 and 459 cm-1 away from the laser line. Draw a representation of the Raman spectrum of CCl4 that includes both the Stokes and anti-Stokes lines.
    6. Why do the anti-Stokes lines of carbon tetrachloride have the following order of intensity: 219 > 314 > 459 cm-1?
