摘　　要：Rh(acac)(CO)_2是烯烃氢甲酰化、氢硅化及一氧化碳加氢反应重要催化剂.晶体具有红绿二色性·在4000至80cm^(-1)范围测定了其红外和拉曼光谱;采用简化的一般价力场(SGVFF),对观测谱带进行了简正坐标分析。1 实验方法Rh(acac)(C0)_2按文献方法合成,并重结晶。红外光谱:用CsI压片在P-E 983G红外光谱仪上测试了4000～180cm^(-1)范围内的光谱,分辨率2cm^(-1).550～80 cm^(-1)波段在Digilab FTS-20E/D-V真空型傅氏光谱仪上得到。The Raman and infrared spectra of dicarbonyl (acetylacetonato) rhodium have been measured form 4000 to 80 cm^(-1). A normal coordinate analysis was performed for all modes by using Simplified General Valence Force Field. 38 force constantswere used during the calculation process. Some new assignments of bands have beenmade and they were supported by some proofs.The reliabilty of result was discussed.
