Refinements in the instrumentation of a diode-laser heterodyne spectrometer permit the rapid and routine measurement of infrared absorptions lying within 6.5 GHz of a CO2 laser emission to a precision and accuracy well within 10 MHz. Measurements on 1,1-difluoroethylene, which is used in optically pumped submillimeter-wave lasers, illustrate the technique.
