Etude des bandes fondamentale ν1 et première harmonique 2 ν1 des haloformes CHF3, CHCl3 et CHBr3 à l'état gazeux

Abstract
Some rotational and vibrational constants in the ν1(CH) and 2ν1(CH) bands of gaseous CHF3, CHCl3, and CHBr3 have been determined. Intensity measurements of these bands are obtained and perturbations in some bands of haloforms are pointed out.
