The absorption coefficient of the wurtzite-type GaN is described in terms of three almost totally decoupled excitons A, B, C associated with split valence bands of Γ_{9}, Γ_{7} and Γ_{7} symmetries using a spherically symmetric approximation for the standard effective-mass Hamiltonian. The excitonic equations are solved within the subspace of optically active states of s-symmetry. The effects of crystal field and spin-orbit coupling are discussed. The results show that the spherical approximation is in perfect agreement with experimental findings.
