The electronic spectrum of Li4CoCl6.10H2O was recorded at liquid nitrogen temperature in the 4,000–25,000 cm?1 spectral region. The simi larity of this spectrum to that of CoCl2 permitted us to assume Oh syn metry of the [CoCl6]4? cluster in our sample. The band assignment was performed in the crystal field approximation using Tanabe and Sugano's energy matrices for Dq = 730 cm?1, B = 820 cm?1 and C/B = 4.4.The large number of bands and high intensity of the maxima in the regio 19,000–21,000 cm?1 is discussed. 相似文献
