Abstract
The magnetic circular dichroism (MCD) spectra of type I and type II diamonds at low temperatures have been measured. The MCD spectra of the GR1 band, produced by irradiation, were the same in both types of diamond and support its assignment to the 1E to 1T2 transition at a neutral vacancy. Values for the MCD parameters A1/D0 and B0/D0 have been calculated from a moments analysis of the spectrum and a value of g=1.68*10-2 has been obtained for the excited state 1T2.Keywords
