Question
3. Identify C-Cl stretching peaks in CDC13 and CHC13 spectra. Do these peaks
have exactly the same frequencies for both compounds? Explain your answer.
4. Is the C==O stretching frequency the same for acetone and deuterated acetone?
Explain your answer.
5. Identify C==O overtone in acetone spectrum which corresponds to the transition
from ground level, n=0, to the second excited level, n=2.
