Abstract: Infinitesimal Cherednik algebras are continuous analogues of rational Cherednik algebras, and in the case of $ \mathfrak{gl}_n$, are deformations of universal enveloping algebras of the Lie algebras $ \mathfrak{sl}_{n+1}$. In the first half of this paper, we compute the determinant of the Shapovalov form, enabling us to classify all irreducible finite dimensional representations of $ H_\zeta (\mathfrak{gl}_n)$. In the second half, we investigate Poisson-analogues of the infinitesimal Cherednik algebras and generalize various results to $ H_\zeta (\mathfrak{sp}_{2n})$, including Kostant's theorem.
