^{N}. The Plancherel measure gives the spectral distribution of the eigenvalues ω

_{λ}of the Hodge-de Rham operator Δ = dδ + δd. The spectrum of Δ is purely continuous except for N even and p = 12N. For N odd the Plancherel measure μ(λ) is a polynomial in λ

^{m}, we give the spectral decomposition of the spin bundle under the action of the fundamental 4-form Ω. Moreover, we compute the eigenvalues of Ω which, in the compact case, play an essential role in the problem of estimating the eigenvalues of the Dirac operator. The proof is based on the decomposition of the spin representation into irreducible...
