We have found that there are regularity changes in the Raman spectra of grossular-andradite as the rise of iron in the crystal structure from grossular to andradite after studying of Raman spectra of grossular-andradite, that is to say, their peaks shift to low wavenumber; At the same time , there are some changes in the bond angles of O-Si-O and O-Y-O:the higher of iron contents, the evidenter of splitting of two wind vibration peaks of SiO4 tetrahedron and YO6 octahedron.

通过对钙铝榴石-钙铁榴石的拉曼光谱研究发现，从钙铝榴石到钙铁榴石，随着矿物结构中铁的含量的增加，他们的拉曼光发生规律性的变化，即所有的峰向低波数方向发生漂移；同时，由于铁含量的不同使得石榴石晶体结构中O-Si-O与O-Y-O之间的键角发生了一定的变化，在其拉曼光谱谱图上表现为铁的含量越高，[SiO4]四面体和Y-O八面体的两个弯曲振动峰分裂得越明显。
