X-RAY STRUCTURAL STUDIES OF LIQUIDS AND THEIR SOLUTIONS

The method of analysis of experimental intensity distribution curve of X-ray scattered radiation is presented on the example of liquid 1,3,5-triphenylbenzene C6H3(C6H5)(3). The experimental curve obtained for 1,3,5-triphenylbenzene was normalized with respect to two theoretical curves of radiation intensity distribution derived for two different models of the molecule. The curve of reduced radiation intensity was analysed by the reduction method. In the present study, we conducted X-ray diffraction experiments for the first time on 1,3,5-triphenylbenzene, in combination with the method of Blum and Narten. The mean amplitudes of vibration were studied in detail. For the first time, the theoretically predicted model of the 1,3,5-triphenylbenzene structure was experimentally confirmed. The structural data obtainable by X-ray analysis for the studied liquid were discussed. Conclusions concerning the most correct interpretation of experimental data were pointed out.
