The formation of blue ferrocenyl cation formed as the intermediate during the mediated reduction of NO is confirmed by spectral method and by generating the blue ferrocenyl cation by the chemical oxidation of dichromate in sulphuric acid.
The synthesized polyimides were studied by spectral methods (UV, IR), thermal analysis and molecular modeling.
New thermoplastic host copolymer based on oxanorbornene dicarboximides for solid polymer electrolytes was synthesized and characterized by spectral methods.
Two different novel heterocyclic compounds namely 2,5-bis(1,3-diphenyl-4,5-dihydro-1H-pyrazol-5-yl thiophene (Material I) and 2,5-bis(3-(naphthalen-1,3-diphenyl-4,5-dihydro-1H-pyrazol-5-yl thiophenene (Material II) were designed, synthesized and characterized by spectral methods.
Besides, a new compound, clematomandshurica saponin F was isolated for the first time and confirmed as a new triterpenoid saponin by spectral methods (MS, 1H NMR, 13C NMR, COSY, DEPT, HMBC, HSQC and ROESY).
The norbornene derivative monomers and the corresponding ROMP polymers were fully characterized by spectral methods.
Structure and UV induced photopolymerization of the macromers were investigated by spectral methods.
The structures of intermediate polymers were analyzed by spectral methods (1H NMR, FTIR).
The chemical structure of all new compounds was confirmed by spectral methods (1H NMR, 13C NMR, IR, MS).
With the decrease of regional scale, the accuracy of estimation by spectral methods will decline (Pérez-Gussinyé et al. 2004).
