摘要：

Raman scattering and mass spectra of n-propanol and p-dioxane mixtures have been measured in order to study diluted effects on n-propanol. The results of both high frequency Raman spectra and mass spectra show the rapid decrease of clusters of hydrogen bonded molecules with decreasing n-propanol mole fractions (X(np)). In the low frequency Raman spectra, line shapes were analyzed using the mode coupling theory, it is found that the minimum frequency of the imaginary part of dynamic susceptibility, omega(min), becomes lower with decreasing x(np). These concentration dependencies suggest a strong relation between the slow structural relaxation and the network structure of molecules in n-propanol.
