ABSTRACT:
A method and apparatus for the spectroscopic observation of particles, such as molecules, transient molecules or atoms, molecular complexes, etc., including a Fabry-Perot cavity having a resonant frequency, a source of pulsed particles to be investigated, such as a pulsed supersonic nozzle beam applied to the cavity, while simultaneously applying a radiation pulse to the cavity sufficient to polarize the particles and provide a coherent radiation emission over a frequency band centered at the cavity resonant frequency, and observing the coherent emission frequencies which are characteristic of the respective particles within the pulsed particles applied to the cavity.
