Alcohol exhibits quantum effects | EurekAlert! Science News

Skoltech scientists and their colleagues from the Russian Quantum Center highlighted the important role of quantum nuclear effects in the polarization of alcohol in an outdoor electric field. The results of their research are published in Journal of Corporate Chemistry.

Molecular lifts, such as water or alcohol, are known to be polar. Polarity is due to the tax separation method, and some questions remain open in the microscopic description. In fact, the basic description of the polarization lies on the concept of one hundred years: the dielectric polarization is related to the molecular dipole moment due to their hydroxyl action group (-OH). The directions of these dipoles were explained by the high polarizability of alcohols and the corresponding high dielectric stability. However, the difference between the measured dielectric dimensions and those determined by computation indicates that other devices that have not been evaluated to date may also play an important role. Since the exact mechanism of dielectric reaction of alcohols is still uncertain, new ideas should be proposed and tested.

“To address the problem, we conducted an experimental study and compared the dielectric responses of a series of monohydric alcohols with different molecular chain lengths and found amazing things that could not be explained by the usual method of circulating molecular tumors. , “said Dr. Ryzhov, the Skoltech Research Scientist in charge of the experimental part of the study.” Despite the conventional wisdom, we have found that basic equipment is a quantum mechanical nature. the dielectric polarization in alcohol: excessive tunneling of proteins resulting in the formation of intermolecular dipoles with proton holes. These dipoles are the ones that determine the dielectric response from dc up to THz, regardless of molecular geometry, so direction “, adds Professor Ouerdane of the Skoltech Center for Energy Science and Technology (CEST) “Our research provides new insights into the properties of smelting dielectrics. The main idea of ​​our model relates to a modern understanding of the disadvantages of dielectric polarization in polar elevators using nuclear quantum effects, ”concludes Vasily Artemov, Senior Research Specialist at Skoltech and lead group author of the paper.
