BANDE DE VIBRATION–ROTATION ν1 + ν4 DE L'IODURE DE MÉTHYLE TRIDEUTÉRIÉ VERS 4 500 cm−1 : MISE EN ÉVIDENCE D'UNE RÉSONANCE DE FERMI

Abstract

The perpendicular band (ν1 + ν4) of CD3I was recorded with a Czerny-type spectrometer, the resolving power of which was about 80 000 in the spectral range. Some rotational constants have been found, and the Fermi resonance between the ν1 + ν4 and ν4 + 2ν5 components pointed out.
