摘　　要：研究了KB5O8·4H2O水溶液20℃时的差示FT-IR光谱和Raman光谱,对振动频率进行了归属。探讨了KB5O8·4H2O水溶液中硼氧配阴离子的存在形式(主要是B(OH)3、[B3O3(OH)4]-和[B5O6(OH)4]-)和相互作用。FT-IR differential and Raman Spectrum of an aqueous solution of KB_5O_8·4H_2O were recorded at 20℃.Fundamental vibrational modes were identified and the assignment of vibrational bands were also made.Both the main borate anions(B(OH)_3,[B_3O_3(OH)_4]^- and [B_5O_6(OH)_4]^-) and their interactions in the aqueous solution have been proposed.
