4.1 Introduction

The word “chirality” is derived from the Greek root “ χειρ ” meaning
“hand”. Thus, the term “chirality” denotes such a property of an
object that is also a property of the human hand. This term was
introduced by lord kelvin in his famous Baltimore Lectures: “I call
any geometrical figure, or any group of points, chiral, and say it has
chirality, if its image in a plane mirror, ideally realized, cannot be
brought to coincide with itself” [34]. This definition implies that,
first, “chirality” is the geometric property of an object; second, only
spatial, that is, three-dimensional, objects possess this property.
Planar (two-dimensional) or linear (one-dimensional) objects do
not possess this property in a three-dimensional space.
