The absorption spectra of Ti (d 2 ), V (d 3 ), Cr (d 4 ), Fe (d 6 ), Co (d 7 ), Ni (d 8 ), and Cu (d 9 ) in CdSe crystals are presented. The main features of the spectra are successfully interpreted using crystal‐field theory for the states of 3d n configuration in a potential of predominantly T d symmetry. It is found that the oscillator strengths of the observed absorption bands are in the range 10 −2 to 10 −5 due to transitions within the 3d n shell. The crystal‐field parameters, Δ , and the Racah parameters, B and C , are determined where possible, and discussed.
