Even with the advent of advanced microscopes, the study of the molecular world remains a challenge for scientists. A group of European researchers for the first time in history managed to record the process of rotation of molecules. In the future, this discovery will help in the study of quantum physics and can be used to monitor various biochemical processors at a previously inaccessible level.
During the rotation of the molecule, there is a change in its magnetic properties, which can be observed with the help of special laboratory equipment. One revolution takes a negligible amount of time — about a trillion fraction of a second. Directing laser pulses directly into the molecule of the carbonyl carried, which consists of atoms of oxygen, sulfur, and carbon, scientists have been able to get it to rotate in unison with the oscillation frequency of the laser.
With the help of an auxiliary laser, the position of the molecule in space was determined. The experiment had to be repeated many times: under the influence of the laser, the "test subject" was completely destroyed. 651 making the scientists managed to create a short "movie" with a duration of 125 picoseconds.
All seen processes obey the laws of quantum mechanics and differ from the usual human laws of the macrocosm. Determination of the exact position and momentum of the molecule in the usual sense is impossible: the video shows the probability of the location of the molecule over time. Scientists believe that this method of observation is suitable for other processes: for example, to study the internal twisting of molecules or "mirror" compounds that are used in biochemistry and chemical technology.
