| Abstract: | High resolution measurements of the far-infrared lattice gap modes due to BH4? in KI are reported. The observed bands at 85.45 ± 0.05 and 84.94 ± 0.05 cm?1 are ascribed as resulting from the presence of two stable boron isotopes in the BH4? ion. The gap modes are calculated by allowing for the elastic relaxation of the lattice around the impurity. The results of a calculation for the Br? gap modes in KI are also presented. |
