I have gone to the website http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi which has been highly recommended for IRs. 

I have found the compound I need to identify. 

I am trying to determine various bonds, ie. C=O, etc.  I notice there is a box at the bottom of the IR Spec. which has information for specific wavelengths (I assume) but I can't find an index or anything to tell me what the numbers represent.  For example, I see 3600 (which I assume is the wavelength) and then a second number like 44 beside it (not sure what this is).

Anyone familiar with this site?

The first number (3600) is the wavenumber (frequency) in cm^-1 and the next number (40) is relative to the intensity (measured in % Transmittance - converted from absorbance) of the observed peak on a scale from 0-100 from bottom to top.
