Realizing that this method would not work for more weakly bound dimers, they began construction of a pulsed molecular beam Fabry-Perot cavity Fourier Transform Microwave Spectrometer (FTMW) which had recently been developed by Bill Flygare's group at the University of Illinois (commonly known as the Balle-Flygare instrument (117).
Two millimeter-wave sensors were onboard: the Electrically Scanning Microwave Radiometer (ESMR) operating at 19.35 GHz, and the Nimbus-E Microwave Spectrometer (NEMS) operating five channels at 22.235, 31.4, 53.65, 54.9 and 58.8 GHz.
In the mid-1990s, Jager and his research team spent nearly a year building a Fourier transform microwave spectrometer. It took another year to add a powerful terahertz radiation source.
