    Abstract:

    We have constructed a conventional far infrared spectrometer based on terahertz (THz) radiation as a spectral source. The THz radiation is generated by focusing a femtose cond pulse onto a semiconductor substrate placed in a strong magnetic field. Far infrared spectra of various condensed phase systems including neat liquids, supercritical fluids, a charge-transfer complex solution, and a protein solution have been measured by this spectrometer.
