Instruments 400-1200 GHz range Example of broadband molecular spectrum study
Spectrometer with submillimeter-wave frequency synthesizer and LHe bolometer.
Example of broadband molecular spectrum study in the Terahertz range.
A portion of the DSSD spectrum containing rQ6 branches of ground and first and second excited torsional states of the molecule (upper picture). Record with increased resolution, showing the ground state rQ6 branch (middle picture). Head of the rQ6 branch with further increased resolution (lower picture).
