Work in laboratories over the last three years has demonstrated that PhotoAcoustic Infrared Fourier Transform (PAIFT) spectroscopy provides unique qualitative and quantitative information about the surface functionalities of bituminous coals. The authors report evidence detected by PAIFT techniques of new carbonyl-type oxygen functionality in such coals, which is generated both by base-promoted and thermal decomposition of precursor peroxide species, which the authors propose are ubiquitous constituents of the surfaces of all except the most freshly prepared samples of powdered bituminous coals.
