Physical Properties of Liquid Nitro Compounds

Heat of combustion (-AH) and oxygen balance of nitroalkane have an linear relationship [2], obeying the enthalpy equation with an error within 1.8 %. 

As shown in Fig. 4.1, similar nitro compounds with substituted carbon atoms at different positions have different infrared absorption peaks. Infrared absorption peaks of different nitro compounds are shown in Table 4.1. 

Note Aa is the wavenumber of the two vibrations, therefore, the number of nitro groups can be determined according to Ao
