Abstract
For the purpose of the wavelength scanning spectroscopy in the millimeter wave region, the authors have made a wide band oscillator using the Ledatron tube. The pulsed output signal is obtained in the wavelength range from 2. 6 to 9 mm (1. 1 to 3. 9 cm** minus **1) almost continuously. The peak output power is over several hundred milliwatts from 4 to 9 mm and over several tens of milliwatts from 2. 6 to 4 mm. With this source, a spectrophotometer has been constructed in which light pipes are used as wave guides and the fluctuation of the signal is averaged by a boxcar integrator. A measurement of absorption spectra is demonstrated for a solid state sample of NaCl:OH** minus .
