本實驗試圖以偏振拉曼 (polarized Raman) 光譜方法研究[N(C2H5)4]2ZnCl4、[N(C2H5)4]2CuCl4、[N(C2H5)4]2CoCl4和 [N(C2H5)4]2ZnBr4四種單晶在相變前後的光譜變化，找出這四種單晶的相變機制。並且藉由電子順磁共振(EPR)的譜圖研究，找出和[N(C2H5)4]2ZnCl4晶體相變有關的機制。經實驗結果，發現[N(C2H5)4]2ZnCl4、[N(C2H5)4]2CoCl4和[N(C2H5)4]2ZnBr4三種晶體的相變與陰、陽離子的無序性有關，且相變溫度隨陰離子的活化能的減小而降低，屬有序-無序相變；而[(NC2H5)4]CuCl4晶體的相變為振動外模軟化所致，為二階或一階相變。
