Some Important Contributions:
Janine Connes's analysis of the technique of Fourier Transform Infrared Spectroscopy was of major significance and laid the foundations of what was to grow into a significant new field. Her thesis work and subsequent publications gave in-depth theoretical analysis of numerous practical details necessary for this experimental technique to work. All the more remarkable is that her work predates the age of digital computers, which now make fast Fourier Transforms relatively routine.
Together with her husband Pierre Connes, she presented spectra of Venus and Mars that were superior by several orders of magnitude than the best available in her time. These measurements, made in the near infrared, through the atmosphere, were extremely difficult and indeed, would not have succeeded without the attention to detail and the remarkably detailed theoretical analysis of the method which she had established.
Janine Connes's research set the ground work for the entire FTIS method now widely used in spectral analysis.
"A very significant contribution to the theoretical and experimental
development of Fourier Transform Infrared spectroscopy. Instrument
developed were used for observation of the night sky. The advantage of
such instruments in having an accurate laser-referenced frequency scale
is referred to as the `Connes advantage.'" [Mary R. Masson]
