Study On The Effect Of Strong Vibration Coupling On The Kinetics Of Sucrose Hydrolysis

Over the past decade,considerable interest has been aroused in the possibility of manipulating chemical and material properties using the polarized states of light and matter.Placing molecules in optical cavities that resonate with molecular transitions creates polarized states of light and matter.Importantly,the generation of this polarized state can occur even in the dark,as the process involves zero fluctuations(i.e.,vacuum fields)and molecular transitions in optical modes.In other words,compared to photochemistry,this phenomenon does not require real photons to occur,which we call strong coupling.Strong coupling in general,and vibrational strong coupling(VSC)in particular,offers exciting research in molecular science and materials science more broadly.Not only is it a new tool for controlling biological reactions,but it also gives us an idea of the vibrations involved in the reactions.There are still many aspects of research related to strong coupling of vibration,both theoretical and experimental,that have not been covered,and only a dozen reactions have been reported so far due to the steep learning curve of using VSC.The study of the effects of biological reactions has only found changes in the activity of gaspase and α-chymotrypsin activity by the strong coupling of water,and these experiments are not easy to perform correctly,so there are few articles on the effect and theory of strong coupling of vibration on reaction rate in basic biological reactions.This paper mainly studies the effect of vibrational coupling of O-H stretching on the hydrolysis reaction of sucrose.To do this,we first designed a usable liquid cell to set up a chamber for easy analysis and observation.The modification of the individual components in the liquid cell is then studied to construct a Fabry-Perot cavity,in which molecules interact with the cavity to couple.Through continuous study of the strong coupling conditions,the molecules resonate with the optical cavity to achieve strong coupling to change the molecules,and finally the infrared spectrometer and ultraviolet spectrophotometer are used to monitor the refractive index-induced displacement of the Fabry-Perot cavity,in which the catalytic efficiency of sucrose hydrolysis can be increased by at least two times.Finally,the effect of VSC on ATP hydrolysis reaction was also studied,and it was found that the catalytic efficiency of ATP hydrolysis was also improved.Finally,the results of this paper show that VSC can be used as a spectroscopic tool to understand the mechanism of enzyme reactions,and also provides new evidence for applications in life sciences,which is expected to improve the enzyme industry,which is of great significance.
