Fourier Transform Microwave Spectrometer Block Diagram Below is a block diagram of the fourier transform microwave spectrometer. The spectrometer consists of a Fabry-Perot cavity made with two spherical mirrors inside a large steel vacuum chamber.  Molecules are pulsed into the cavity using a solenoid value and Teflon nozzle.  Microwaves are pulsed into the cavity, which excites the molecules and when they decay back to a lower state, they emit radiation, which is detected as a free induction decay (FID).  This FID is fourier transformed into a spectrum in frequency.   This spectrometer is currently in development and many improvements and new techniques will be used in future work.
