Vibrational Spectroscopic Analysis Of Polycrystalline Deuterium Oxynitrate

A number of polycrystalline samples in the“M₂?OH/D?₃X”of a novel geometric containment material containing hydrogen bonds have been tested at low temperature,thermal,electrical,infrared and Raman spectroscopy at home and abroad.The physical phenomena such as spin liquid state,spin glass state and singular quantum ground state related to magnetic geometric frustration are found.Similar studies of similar M₂?OH?₃NO₃ series materials were also performed,including the vibration spectrum-infrared and Raman spectroscopy analysis as a basis for the study.However,the analysis of the vibration of M₂?OH?₃NO₃series materials is not sufficient,especially in combination with the necessary auxiliary analysis of the compound M₂?OD?₃NO₃,so there is a problem that the vibration and spectrum analysis is not accurate.In view of a series of problems existing at present,this paper has done the following work:First,the hydrothermal synthesis and the normal temperature synthesis of Cu/Ni₂?OH?₃NO₃ samples were carried out.Second,because Cu/Ni₂?OH?₃NO₃ samples synthesized at room temperature were spread,the peaks were covered,and the hydrothermal synthesis of the Cu/Ni₂?OD?₃NO₃samples was carried out.Third:The basic physical properties of Cu₂?OH/D?₃NO₃ and Ni₂?OH/D?₃NO₃samples were analyzed?scanning electron microscopy test as well as thermogravimetric analysis experiment?.Fourth,the infrared and Raman spectra of Cu₂?OH/D?₃NO₃ and Ni₂?OH/D?₃NO₃were analyzed,and they were divided into four regions to analyze:?1?infrared and Raman spectral analysis of OH/D functional group region,?2?infrared and Raman spectral analysis of NO₃ functional group region,?3?infrared and Raman spectral analysis of the correlation peak region of OH/D,?4?infrared and Raman spectral analysis of fingerprint region.Fifth:through the scanning electron microscope test results of three kinds of Cu samples and three kinds of Ni samples,the results of thermogravimetric analysis and infrared and Raman spectra analysis show that we have synthesized deuterated samples.It lays a certain foundation for the preparation of deutero-oxygen nitrate by stirring at room temperature,not stirring at room temperature,stirring at high temperature and not stirring at high temperature,so as to study when they can appear obvious deuterium peaks,and to lay a certain foundation for the study of quantum magnetic properties of polycrystalline deuterium and oxygen nitrate.But there is still room for improvement.
