Abstract
The defect molecular model for the vacancy in diamond originally proposed by Coulson and Kersley requires some extension before it accounts for the observed symmetry of the states involved in the GR1 doublet. Models involving spin-orbit interaction and also Jahn-Teller effects are examined in the light of recent stress results. It is suggested that the GR1 transitions are between vibronic states in a ground electronic E state and an electronic T states; the latter being weakly coupled to the e modes.Keywords
