Applying the unitary operator (4.65) to the Dirac spinors in the Dirac representation (4.21) (we use c⁻¹ = iσ₂)

we obtain for the corresponding spinors in the Majorana representation

Recalling that

we see from (4.70) and (4.71) that

In the case of Majorana fermions, it is convenient to redefine the phase of the Dirac spinors via the replacements

For this new choice of phase, Eq. (4.72) is replaced by
