The DSR spectrums show the compounds with unpaired electron (with V+4 atom) possess broad absorbed peaks at VIS wave range, and the compounds with only V+5 atom show a obvious absorption edge.

• 研究了12种化合物的紫外－可见固体漫反射光谱、稳态荧光光谱性质。 紫外－可见固体漫反射光谱显示具有未成对电子(即含有+4价钒原子)的化合物在可见波段有宽的吸收峰，而仅具有五价钒的化合物的紫外-可见固体漫反射光谱具有明显的吸收边。
