How do we detect chirality

WebFundamentals of Chirality Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity. One of their most interesting type of isomer is the mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror image of one another. WebJun 9, 2024 · In the knot theory lessons (and in wikipedia) it is stated that "The Alexander polynomial cannot detect the chirality", and it may be the case, but what worries me is that it is sometimes deduced right afted showing that Δ ( K) = Δ ( K ∗), where K ∗ is the mirror image of the knot K.
