Meanwhile,in order to make the Raman assignments to the TMU molecular.the calculated TMU Raman rfequency was compared with its Raman frequency that was measured in experiment.The frequent shitf of TMU—aqueous binary solution at different concentration was measured by Raman rilethod。 Under the influence of special interactions(hydrogen band)and steric hindrance of the associated water molecule:when this ratio was lower than 2,the frequency changes of stretching vibration of carboxyl in TMU was linear proportion to this ratio:when this ratio was larger than two.the frequency of stretching vibration of carboxyl was a constant at l 585 cIn 1。。 Under the influence of non.special interaetions of solvent effects,other vibrati0n frequencv change was smal1.
