Naproxen is non-steroidal anti-inflammatory and antipyretic analgesic with minor side effects currently,but the NMR spectra of Naproxen have not been assigned absolutely. NMR technique is an important tool of molecular structure analysis. In order to analyze the molecular structure of Naproxen,the NMR spectra of Naproxen were tested with 2D-NMR and 1D-NMR techniques, such as ^1H NMR、^13C NMR、DEPT-135、^1H-^1H COSY、HSQC、HMBC、^1H-^1H NOESY,and it realized the complete assignment of ^1H-NMR and13C-NMR. Furthermore,it was successful to analyze the H atom and C atom,specially quaternary carbon of naphthalene ring completely. These experiments would help to fill in the blanks of 2D-NMR experimental teaching in the instrumental analysis experiments and facilitate to master the 2D-NMR analysis of organic compound structure for students,which had an important significance for correct structure analysis of organic c
