The article is divided into three parts: The first part describes the crystal and molecular structure of the aryl sulfone CH3CONHC6 H4SO2 R (R = CH3, CH2 CONH2, CH2 CH2 OH) measured by a four-circle diffractometer using X-ray single crystal diffraction Results; In the second part, the results of the test on the bond angle and bond length in the molecule were analyzed to prove the existence of the hyperconjugation effect in the molecule of the sulfone. It is explained that the specificity of the infrared absorption of the molecule of the methylsulfone is determined by the content of the methylsulfone group Superconjugation effect caused, found the infrared peak of the certified methyl sulfone, and revealed some of the characteristics of hyperconjugation effect; the third part describes the synthesis of aryl sulfone, the preparation of the crystal, the crystal test
