Infrared Spectrum Analysis of
Fuzimin 1-octanol (1-Octanol) The infrared spectrum (Ir Spectrum) requires detailed investigation of its spectral peak characteristics. At the wavenumber of about 3300-3400\ (cm ^ {-1}\), a wide strong absorption peak is common, which is caused by the stretching vibration of hydroxyl (\ (-OH\)). In alcohols, the hydrogen bond of hydroxyl groups makes the vibration absorption peak appear widened, and the existence of this peak is a clear evidence that 1-octanol contains hydroxyl functional groups.

Furthermore, in the range of 2800-3000\ (cm ^ {-1}\), several absorption peaks can be seen, which are generated by the stretching vibration of saturated carbon-hydrogen (\ (C-H\)). 1-octanol is a straight-chain saturated alcohol, and the vibration of a large number of saturated carbon-hydrogen bonds in the molecule shows characteristic absorption in this wavenumber range.

And near 1460\ (cm ^ {-1}\) and 1380\ (cm ^ {-1}\), there are also absorption peaks, corresponding to the bending vibration of methyl (\ (- CH_ {3}\)) and methylene (\ (- CH_ {2} -\)), respectively. In the molecular chain of 1-octanol, the structural characteristics of methyl and methylene are revealed in infrared spectroscopy.

Through the analysis of each absorption peak of 1-octanol infrared spectroscopy, the information of functional groups and chemical bonds contained in the molecular structure can be gained, which is of crucial significance for the structure identification and analysis of organic compounds.
