A rhodamine <i>B</i> quantum counter and a thermopile were used to calibrate a grating monochromator and photomultiplier for the measurement of corrected emission spectra from 240 to 600 mµ. The calibration was checked over a limited wavelength range with a standard tungsten lamp. Fluorescence spectra determined with the instrument agree well with previously reported spectra.
