    After working through the theory and examples, you can now self assess your understanding of IR spectroscopy by completing the problems.
    Characteristic IR Absorption Frequencies
    You will need to consult the characteristic frequencies table.

    1. The IR spectrum of butanone is shown below. What are the approximate wavenumbers of the stretching absorptions due to the C-H and C=O bonds?
     
    IR spectrum of butanone  
    (a) C-H: cm-1

    (b) C=O: cm-1


    (This question is for self assessment and your answer and score will not be recorded.)
