Variations in organic structure of vitrinite concentrates were determined with Fourier transform infrared spectroscopy (FTIR). FTIR is a relatively new method for obtaining quantitative data from the organic constituents of coal and provides spectra of greater quality than conventional infrared spectrometers. The system employs an on-line minicomputer which enables the user to analyze data and perform a variety of mathematical manipulations. [Pg.103]
