Study of the dispersion in the 3.4$\mu$ and $\lambda .f\mu$ vibration-rotation bands, using a Twyman interferometer in connection with a grating spectrometer. Determination of the coefficients $M0$, $M1$, and $M2$ in the expansion of the dipole moment with respect to the variation ($r-re$) of the internuclear distance. {M}(2)={M}{0}+{M}{1}({r}-{r}{e})+{M}{2}({r}-{r}_{e})^{2} The data is from the research of F. Legay of our laboratory.
