Title: Spectre infrarouge à l'état solide des molécules isotopiques de $SO_2$
Abstract: We have observed the infrared absorption spectrum of the isotopic molecules of $SO_2$ with the natural abundance for sulfur-32 and -34 and oxygen-16 and with oxygen-18 at 97 per cent containing 0.4 per cent oxygen-17. We show that the preceding augments of bands [5], [6] are erroneous. The bands previously augmented to the interaction of the internal vibrations and the lattice vibrations are due to isotopics bands. On the other hand the form of band when the molecule is diluted in isotopic molecules and when it is surrounded by identical molecules shows that there is in intermolecular coupling. The great number of bands observed enables us to calculate the force constants in the solid state using the most general quadratic force field. We compare these force constants in solid state with those obtained in the gaseous state [10] and in the solid state in a Krypton matrix [7].
