Bunte recommended that Haber take a look at the thermal decomposition of hydrocarbons. By building very careful quantitative analyses, Haber was capable to determine that "the thermal balance of your carbon-carbon bond is larger than that from the carbon-hydrogen bond in aromatic compounds and scaled-down in aliphatic compounds", a typical haber1903 end in the study of pyrolysis of hydrocarbons. This operate grew to become Haber's habilitation thesis.[12]: 40
