Aaron King 660556233 Section 2 #10 Introduction to Infrared Spectroscopy 1. The calculated bond vibration frequency for a carbon-hydrogen single bond is 3017cm -1 . The observed vibration frequency for the carbon-hydrogen single bond in octane is 2924cm -1 . The calculated bond vibration frequency for a carbon-oxygen double bond is 1573cm -1 . The observed bond vibration frequency for the carbon-oxygen double bond in octanal is 1728cm -1 . The calculated bond vibration frequency for a carbon-oxygen single bond is 1112cm -1 . The observed bond vibration frequency for the carbon-oxygen single bond in octanol is 1058cm -1 . 2. The wavelength is proportional to the frequency. 3. The IR peak at about 2500cm -1 differ in the two spectra.

Unformatted text preview: Also the IR peak in the deuterated octanol around 3300cm-1 that does not exist in the regular octanol. The reasoning behind this is because in the deuterated octanol, the oxide is attached to the second carbon in the chain instead of the first. 4. Yes, it agrees with the theory introduced in the pre-lab. The accepted frequency for carbon-oxygen single bonds is between 1300-1100cm-1 . Also, the accepted frequency for a hydroxide bond is about 3400cm-1 . 5. An error could have occurred if the plates were not cleaned properly. It is necessary to evaporate the acetone wash solvent from the slat plates before adding the sample. If this is not done, the results will show the acetone carbonyl....
