摘要：
Adopting raman spectrometer to conduct qualitative and quantitative analysis of m-cresol and p-cresol, selecting the respective character peak of bencycloquidium after deformation vibration (m-cresol at 732 cm(-1) and p-cresol at 841 cm(-1)), via experiment and calculations, the relative raman (partial derivative sigma/partial derivative Omega)(732cm-1)/(partial derivative sigma/partial derivative Omega)(841cm-1) cross section of m-cresol and p-cresol can be concluded: is 0.74 (height-fitting of the peak), and 0.61 (area-fitting of the peak). This method samples simply and rapidly, and has a short testing time, whose quantitative analysis result of m-/p-cresol is consistent with that of GC analysis.
