NEW DETERMINATION OF INFRARED WAVELENGTH STANDARDS BY VACUUM FOURIER SPECTROSCOPY

Abstract

Author Institution: Laboratoire Aim\'{e} Cotton, C. N. R. S. IINew wavelength standards are obtained in the $2000 cm^{-1}$ spectral region. They consist of lines belonging to the vibration-rotation spectra of $H_{2}O$, $CO_{2}$, CO molecules and some of their isotopic species. Their measurement has been performed with reference to the krypton - 84 Length Etalon by using 2-0 CO band lines previously determined on the same apparatus with an estimated relative error of 3 $\times$ 10$^{-8}$
