DILUTED EFFECTS ON N-PROPANOL

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