We use electronic Raman scattering for studying the band structure of the nsns boron acceptor states in diamond. For the first time, the spin–orbit splitting of these acceptor states and the 1s→ns1s→ns Lyman series of transitions are observed. The spin–orbit splitting linearly increases with n number. Lyman series exhibit fine structure consisting of four bands each. The energy spacing between series is equal to ∼13 meV∼13 meV. Evolution of Raman spectra of the boron-doped diamond with increasing boron concentration is shown. Mott transition is revealed in Raman spectrum. Correct values of Luttinger parameters for diamond are specified.
