title: Multiple order spectra in Fourier transform infrared spectroscopy.
abstract: A phenomenon akin to higher order spectra in grating spectroscopy has been found in Fourier transform spectroscopy. While its relative intensity is orders of magnitude down from similar effects in gratings, the high sensitivity of Fourier transform ir allows this perturbation to be detected.
