摘要：

The unusually large temperature effect on the luminescence intensity of some imine chelates of d6 ions of certain group VIII metals can be attributed to the effect on the intersystem crossing rate of a temperature-dependent equilibrium between high- and low-spin states established during the lifetime of the charge-transfer excited state of the chelate. The absence of luminescence from Fe(II)-imine chelates may result from complete crossover to the high-spin state upon excitation. © 1969, American Chemical Society. All rights reserved.
