Spectroscopic apparatus capable of measuring laboratory absorption spectra at medium infrared wavelengths with a resolution of .08 1cm and a precision of .005 1cm was developed. A new double pass system and two prism echelle spectrometers, one a vacuum instrument are described. A computation and quantitative measurement of the radiant power transmitted by the spectrometer was made. These instruments were used to investigate the Fermi Resonance, LL 2 resonance and other phenomena in several isotopic nitrous oxides by a study of the spectra in the 8 and 17 micron regions. Author
