摘要: Abstract An ultraviolet emission spectrum attributed to cyanide ions in alkali halide lattices is excited by VUV irradiation and electron impact, using samples containing isotopically substituted 13 CN − as well normal 12 . Analysis of the yields ground state vibrational constants ω e = 2125 cm −1 χ 14.2 for KCl. The electronic lies 5.6 eV above has room-temperature decay lifetime 80 ms very dilutely doped KCl samples. This value consistent with expectations forbidden triplet-singlet transition, but inconsistent other studies this system.
