Abstract
We synthesized tunable far-infrared radiation at frequencies higher than 9 THz (300 cm(-1)) by mixing CO2 laser, (NH3)-N-15 laser, and microwave radia tion in a W-Co metal-insulator-metal diode. We used this far-infrared radia tion to accurately measure torsion-rotation transitions of CH3OH in the 8-9 -THz region. We also measured the frequency of the aP(7, 3) (NH3)-N-15 lase r transition.
