We report a useful multiparameter Newton–Raphson method, yielding accurate pair‐anisotropy models from a set of low‐order experimental spectral moments. The method is applied to the depolarized binary collision‐induced scattering spectrum of argon. Its reliability is established through comparison between the (Ar) 2 experimental spectrum, previously recorded by our group over a broad wavenumber domain, and quantum‐mechanical profiles whose inputs are various pair‐anisotropy models.
