Abstract

We report on an experimental demonstration of molecular Stark spectroscopy based on the use of tunable far-infrared radiation at 0.91 THz. The radiation was generated by the nonlinear mixing of the radiation from two CO₂ lasers in a point-contact metal–insulator–metal diode. The technique is used to make the first reported measurement of the permanent dipole moment of ¹³CH₃OH; μ_a = 0.883(25) D.
