The E J c and E//c absorption spectra due to the Cu" center in CdCl. andCdBr. single crystals with layer structure have been investigated in the ultravioletregion. The intensities of E f c absorptions in both crystals do not change verymuch with elevating temperature, while those of E//c absorptions increaseappreciably. The oscillator strengths at L.N.T. of E ? c absorptions are estimatedto be 0.016 for CdC]. : Cu" and 0.058 for CdBrz : Cu", and those of E//c absorp-lions are 0.005 for CdC]. : Cu" and 0.012 for CdBrz : Cu", These absorptions areattributed to the forbidden transition (3d)"=(3d)'4s in Cu' ion which becomespartially allowed by the interaction with phonons for E//c, and by locating theCu' ion on an off-center position for E f c.
