The Physics and Spectroscopy of the SMM/THz
To illustrate the rotational fingerprint,
Figure: 20 Gas Mixture. 50 GHz of a spectrum of a mixture of 20 gases on a highly
com-
pressed scale taken with a FASSST BWO based system (top). 0.4% of this spectrum is
exp-
anded to show individual lines (bottom). Comparison with the library spectra of eight
gases
shows their presence in the gas mixture (middle).
