A review is presented of recent developments in the methods of dispersive Fourier transform spectrometry that have demonstrated the unique value of the technique in providing accurate determinations of both optical constants of a material at millimetre and submillimetre wavelengths. These developments are illustrated by reference to the results of measurements on gases, liquids and solids that would not have been possible with more conventional spectrometric techniques, and which have improved our knowledge and understanding of the microscopic behaviour of such systems.
