1bromobutane Ir Spectrum
Analysis of 1-Bromobutane Infrared Spectroscopy
Fuzhuming 1-Bromobutane's properties, infrared spectroscopy is a powerful tool. Looking at its infrared spectrum, all peaks show their own characteristics.
At about 2960-2850\ (cm ^ {-1}\), there are strong and wide peaks, which are caused by the stretching vibration of saturated carbon-hydrogen (\ (C-H\)). In the alkane structure, the stretching vibration frequency of methyl (\ (- CH_ {3}\)) and methylene (\ (- CH_ {2} -\)) is in this range, indicating the characteristics of its intramolecular carbon-hydrogen structure.
At about 1460\ (cm ^ {-1}\), see the medium-strong peak, which is the shear vibration peak of methylene (\ (- CH_ {2} -\)), characterizing the existence of methylene in the molecular chain. And at about 1375\ (cm ^ {-1}\), the symmetrical bending vibration peak of methyl is now the sign of methyl in the molecular structure.
In the range of about 690-515\ (cm ^ {-1}\), there is a peak, which is the stretching vibration peak of carbon-bromine (\ (C-Br\)). Due to the large mass of bromine atoms, its stretching vibration frequency is in this lower wavenumber range. The presence of this peak conclusively proves the existence of carbon-bromine bonds in 1-bromobutane molecules.
Looking at the infrared spectrum of 1-bromobutane, the peaks are mixed and each refers to each other, which confirms each other, allowing us to understand the secret of its molecular structure and provides a solid basis for the identification and analysis of this compound.
