Ca（C8H5O4 ）2·2H2O orthorhombic, （No. 31）, Z= 4, a = 2. 748 2,b= 0. 942 5,c = 0. 692 6 um. Sr（C8H5O4）2·2H2O orthorhombic, （No. 36）, Z= 4, a= 2. 8465,b = 0. 879 8, c = 0. 698 0 um. Ba（C8H5O4）2·H2O monoclinic, -P1a1 （No. 7）, Z = 6,a= 3. 105 1, b= 0. 700 8, c= 1. 178 1 um, β= 100. 55° On this basis, their IR and Raman spectra have been investigated. The effect of coordinate structures of phthalate groups with metal ions in solid sate samples on the vibration spectra have been discussed. 邻苯二甲酸氢盐 碱土金属 红外光谱 拉曼光谱 benzenedicarboxylic acid alkali-earth metal IR spectrum Raman spectrum O627.11 1994-03-01 2021-04-01 3
