Significance: Measurement of the spin can be used to check the purity and content of a cyclotronic substance, and even to determine the reaction rate constant of a cyclotronic substance, i.e., to study the reaction mechanism of a cyclotronic substance.
The significance of the measurement of the rotativity of a cyclic compound is that it is possible to determine the ratio of a specific compound to that of a specific compound. The spinodensity of a substance is a constant, and the ratio of the spinodensity to a specific compound is usually used.
Objects with rotational properties cannot have a structure that is invariant to spatial inversion. For polycrystals or solutions where the molecules can be oriented randomly, the molecules must be chiral.
The rotational properties due to the chirality of the organic molecules themselves are called internal rotations, which are divided into left and right rotations, but if an object has both left and right rotations within it or if the structure of the object molecules themselves have opposite chiralities, the object does not exhibit rotational properties. The molecules that do not exhibit optical rotation because they have both left and right rotations inside the object are called racemic, while the molecules themselves are structured with opposite chirality and do not exhibit optical rotation are called endocyclic.
Molecules with chiral properties are all cyclotropic. Such molecules will be mirror symmetrical like our right and left hands, but will never overlap.
There are many substances in nature that do not affect the vibrational plane of polarized light, such as water, ethanol, acetone, glycerol, and sodium chloride; there are other substances that can deflect the vibrational plane of polarized light, such as a solution of lactic acid and glucose. Can make the polarized light vibration surface deflection of the substance with the rotational properties, called rotational substances.
