Before Analyzing the IR Spectrum:
Identify functional groups present
Write down corresponding bond vibrations (stretches & bends) from the IR table (below)
Write down the expected wavenumber ranges
any C=C or C=O stretches? is it saturated or conjugated?
any C-H bends (alkenes, aromatic compounds)? see Table 2 for narrow wavenumber ranges

Analyzing the IR Spectrum:
Report the observed wavenumber for all of the peaks that fall within the expected wavenumber range
