The Measurement of Infrared Emission Spectra Using Multiple-Scan Interferometryre emission spectra of various substances, The instrument is highly senstive and could be used for transmission, reflection, and emission spectroscopy, especially in situations where the signals obtained are weak.

Frank M. Gresham,Michael P. Careyre essentially independent of any chemical changes occurring within the sample. Analyses of molybdenum, tellurium, manganese, and phosphorus in mixtures have provided results slightly less accurate than by chemical methods, but obtained in much less time.

Frank M. Gresham,Michael P. Careyge in wavelength with a change in ., which is also related to changes in electron distribution. A comparison of shape of emission bands with crystal structure indicates that, in general, NaCl-type structures have symmetrical bands with narrow bandwidths compared to hexagonal structures, which have asymmetrical bands.
