We report the first observation of the electronic Raman effect in semiconducting {ital p}-type, isotopically controlled diamonds. The Raman transition between the spin-orbit split 1{ital s} ground states of boron acceptors occurs at {Delta}{sup {prime}}=2.07(1) and 2.01(1)meV in natural and {sup 13}C diamonds, respectively. Polarization features show the transition to be predominantly {Gamma}{sub 5} in character, placing an upper limit on the ratio of the nonspherical Luttinger parameters of the valence band. Host-isotope-related self-energy shifts are observed in both the electronic infrared and Raman spectra. {copyright} {ital 1997} {ital The American Physical Society}
