本工作中分别在常温和低温(低于-170℃)测定了六种固态双环磷酸酯ZP(OCH_2)_3CR(Z=LP,O,S;R=CH_3,CH_2Br)的红外和拉曼光谱,并且还测定了它们在氯仿溶液中的红外光谱。对固态光谱的解释表明ZP(OCH_2)_3CR分子的对称性低于C_3,其他作者曾报道固态ZP(OCH_2)_3CCH_3的对称性为C_3v。通过比较常温与低温的光谱、固态与溶液的光谱,并对比开环化合物ZP(OCH_3)_2振动频率的已知归属,我们指认了六种化合物的振动频率。双环笼骨架的变形在638—695cm~(-1)产生强的红外和拉曼峰。
In this work, infrared and Raman spectra of six solid-state bicyclic phosphate ZP (OCH_2) _3CR (Z = LP, O, S; R = CH_3, CH_2Br) were measured at room temperature and low temperature Their infrared spectra in chloroform solution were also determined. The interpretation of the solid-state spectroscopy shows that the symmetry of the ZP (OCH_2) _3CR molecule is lower than that of C_3. Other authors have reported that the symmetry of solid-state ZP (OCH_2) _3CCH_3 is C_3v. By comparing the spectra of the normal and the low temperature, the spectra of the solid and the solution, and comparing the known assignments of the vibrational frequencies of the ring-opened compound ZP (OCH 3) 2, we have identified the vibrational frequencies of the six compounds. The deformation of the bicyclic cage produces strong infrared and Raman peaks at 638-695 cm -1.
