IR Analysis.

1. Label each peak and identify the corresponding functional group of guaifenesin in your spectra. Include the literature wavenumber ranges of each functional group as a means of comparison.
2. Look up the literature I spectra of guaifenesin and compare yours with it. How do they differ? What might be the reason?

NMR Analysis.

1. Label each relevant peak, identify its duplicity if possible, and identify the corresponding hydrogens. Label the solvent peak. Include the integration of each peak corresponding to guaifenesin. Include the literature chemical shift ranges of each hydrogen environment as a means of comparison.
2. Look up the literature NMR spectra of guaifenesin and compare yours with it. How do they differ? What might be the reason?
