Although there have been many calculations of the structures of the self-interstitial in Si and small aggregates of interstititals, In, there has been little attempt to relate the defects with experimental data, Here we discuss the assignments of the self-interstitial to the AA12 electron paramagnetic resonance (EPR) centre. and the tri-interstitial and tetra-interstitial to the W-optical centre and the B3 EPR centre, respectively. Difficulties in the assignment of 1, to the P6 EPR centre are also noted.
