Intrinsic chirality of multipartite graphs
We classify which complete multipartite graphs are intrinsically chiral.
متن کاملCompetitive chiral induction in a 2D molecular assembly: Intrinsic chirality versus coadsorber-induced chirality
Noncovalently introducing stereogenic information is a promising approach to embed chirality in achiral molecular systems. However, the interplay of the noncovalently introduced chirality with the intrinsic chirality of molecules or molecular aggregations has rarely been addressed. We report a competitive chiral expression of the noncovalent interaction-mediated chirality induction and the intr...
متن کاملControl of molecular chirality
We present a theoretical study of controlling molecular chirality in chemical reactions by circularly polarized fields. A theory of absolute asymmetric synthesis is formulated by standard perturbation theory. An estimation of the chiral polarization of the product is provided. We show that an unstable chiral configuration can be described as a spin one-half particle. The circularly polarized fi...
متن کاملPolarity reveals intrinsic cell chirality.
Like blood neutrophils, dHL60 cells respond to a uniform concentration of attractant by polarizing in apparently random directions. How each cell chooses its own direction is unknown. We now find that an arrow drawn from the center of the nucleus of an unpolarized cell to its centrosome strongly predicts the subsequent direction of attractant-induced polarity: Of 60 cells that polarized in resp...
متن کاملIntrinsic Chirality of 3-Connected Graphs
Recently, topology and graph theory have come together to study graphs embedded in 3-space, (see for example [1 5]). An analysis of the symmetries of spatial graphs is useful in chemistry in determining when a molecular bond graph is chiral (i.e., distinct from its mirror image). We are interested in classifying those graphs whose intrinsic structure is such that no matter how they are embedded...
