Chirality and helicity are two terms that are often used interchangeably in the fields of chemistry and physics. However, there is a distinct difference between the two. In this blog, we will explore the differences between chirality and helicity, and explain why they are important in the study of molecules and particles.

How chirality and helicity differ
Chirality and helicity are often used interchangeably, but there is an important difference between the two terms. Chirality is a property of an object that indicates it cannot be superimposed on its mirror image. Helicity, on the other hand, is a measure of the spin of a particle.
Specifically, helicity is the projection of a particle’s spin onto its linear momentum. In other words, it is the degree to which the particle’s spin is in the same direction as its motion.
Chirality refers to the handedness of the object, while helicity relates to the particle’s spin.
Examples of chirality and helicity
Chirality and helicity are two terms often used interchangeably, but they have distinct differences. Chirality is a property of an object in which it cannot be superimposed onto its mirror image. Helicity, on the other hand, is a property of a particle that describes the direction of its spin.
To illustrate the difference between the two, consider a right-handed screw. It is chiral because the left-handed version of the screw cannot be superimposed onto the right-handed version.
However, the screw has no helicity because it does not spin. On the other hand, an electron is both chiral and has helicity because its spin has a direction.
Factors that affect chirality and helicity
The terms “chirality” and “helicity” are often used interchangeably, but they actually refer to different concepts. Chirality and helicity are related, but they are not the same. Chirality relates to the overall handedness of a molecule, while helicity is a measure of the twist of the molecule.
Chirality is determined by the number of different atoms in the molecule and the arrangement of these atoms in three-dimensional space. On the other hand, helicity is determined by the relative orientation of the bonds between the atoms.
While these two factors are related, the difference between chirality and helicity is important to understand when studying molecules and their properties.
Applications of chirality and helicity
Chirality and helicity are two related, yet distinct concepts that are important in many scientific fields. Chirality is a property of objects that have a handedness – the ability to be distinguished from its mirror image. Helicity, on the other hand, is related to motion.
It’s the property of a particle or wave that describes the direction of its spin or rotation as it moves through space. This difference is key to understanding both concepts and their applications.
Chirality is often used to explain asymmetry in nature, like the difference between a left and right hand, while helicity can be used to explain the motion of particles and waves, like the spin of a particle or the polarization of a light wave.

The terms ‘chirality’ and ‘helicity’ are often used interchangeably, but they are actually two distinct concepts. Chirality refers to the lack of symmetry in a molecule, while helicity is the property of a particle or wave that describes its “handedness”, or direction of spin. In other words, chirality refers to the physical structure of a molecule, while helicity refers to the direction of rotation of an object.
In other words, chirality refers to the physical structure of a molecule, while helicity refers to the direction of rotation of an object. Although related, chirality and helicity are distinct components of a molecule and should not be confused.
Bottom Line
In conclusion, it is important to understand the difference between chirality and helicity. While they are both related to the properties of a particle, they are distinct. Chirality is related to the handedness of the particle, and is a fundamental property, whereas helicity is related to the spin of the particle, and is not an intrinsic property.
Chirality is related to the handedness of the particle, and is a fundamental property, whereas helicity is related to the spin of the particle, and is not an intrinsic property. Chirality determines the type of particle, while helicity determines the direction of spin.
