We develop an algebraic procedure to rotate a general Newman-Penrose tetradin a Petrov type I spacetime into a frame with Weyl scalars $\Psi_{1}$ and$\Psi_{3}$ equal to zero, assuming that initially all the Weyl scalars are nonvanishing. The new frame highlights the physical properties of the spacetime.In particular, in a Petrov Type I spacetime, setting $\Psi_{1}$ and $\Psi_{3}$to zero makes apparent the superposition of a Coulomb-type effect $\Psi_{2}$with transverse degrees of freedom $\Psi_{0}$ and $\Psi_{4}$.Comment: 10 pages, submitted to Classical Quantum Gravit
