Abstract:
To quantify chiral shape, a tensor describing the particle shape has been proposed. This tensor, named the shape tensor (S-tensor), is an analog of the hydrodynamic tensor that relates the rotational and translational motions of particles in a liquid. The determinant of the S-tensor, named chirality measure density (CMD), was calculated for chiral tetrahedrons and octahedrons. It was found that CMD is opposite in sign when the mirror images are chiral to each other and vanishes when they are achiral. Therefore, the CMD is a good measure to distinguish the mirror images. The interaction between chiral particles was discussed in terms of the CMD.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
