On the Infrared Spectrum of Ethyl Acetate
The IR Spectrum of Ethyl Acetate must be studied in detail in order to achieve a little knowledge.

In the infrared spectrum, the molecule is irradiated by infrared light, and due to the absorption of light energy of a specific frequency, the molecular vibration energy level transition is caused, and then the spectrum is formed. This spectrum is like a human fingerprint, each has its own characteristics, and can be used to characterize the molecular structure.

In the infrared spectrum of ethyl acetate, its characteristic peak is significant. For example, the stretching vibration peak of carbonyl (C = O) is around 1735 cm. This peak is sharp and strong, which is the sign of carbonyl in the structure of ethyl acetate. The stretching vibration of the capillary carbonyl double bond has a large energy change, so the absorption peak is strong. The stretching vibration peak of C-O, which is about 1240-1050 cm ¬ range, is also an important feature. The C-O bond has a certain polarity, which triggers a dipole moment change when vibrating, so it shows this in the infrared spectrum.

Furthermore, the C-H stretching vibration peaks of methyl (-CH 🥰) and methylene (-CH 🥰 -) show multiple absorption peaks in the range of 2980-2850 cm ¬ This is due to the slight difference in the vibration frequency of the C-H bond in different environments. And the symmetric and antisymmetric bending vibration peaks of methyl groups are about 1460 cm and 1375 cm, which are also the key basis for identifying the structure of ethyl acetate.

From this perspective, detailed analysis of the infrared spectrum of ethyl acetate can reveal the mystery of its molecular structure, which is of important guiding significance in chemical analysis, organic synthesis and other fields. Exploring the characteristics of its spectrum, such as clearing the clouds and seeing the sun, makes the truth of the molecular structure clear.
