The Use of a Fabry-Perot Interferometer for Studying Rotational Raman Spectra of Gases

  • J. J. Barrett


A method is described that allows simultaneous observation of a large number of rotational Raman lines of a gas. This method can provide substantial advantages in light economy over techniques using vibrational Raman scattering for the measurement of gas properties. It employs a Fabry-Perot etalon whose free spectral range is adjusted to coincide with the spacing between rotational Raman scattering lines. Principles of operation, construction details of several instruments, and experimental results for several gases are described.
