Alekseev and E. Meinrenken [arXiv: math. RT/0308135] proved that for quadratic symmetric pairs with anti-invariant bilineaire form, Rouvière's formula is still valid by using a deformation of the Weyl algebra. We recover this result by using the orbit method in Lie theory and our generalized Harish-Chandra homomorphism [J. Functional Anal. 117 (1993) 118--173 and 173--214, Bull. Soc. Math.
