Enumeration of Polyene Hydrocarbons: A Complete Mathematical Solution
نویسندگان
چکیده
Polyenoid systems (or polyenoids) are trees which can be embedded in a hexagonal lattice and represent CnHn+2 polyene hydrocarbons. Complete mathematical solutions in terms of summations and in terms of a generating function are deduced for the numbers of polyenoids when overlapping edges and/or vertices are allowed. Geometrically planar polyenoids (without overlapping vertices) are enumerated by computer programming. Thus the numbers of geometrically nonplanar polyenoids become accessible. Some of their numbers are confirmed by combinatorial constructions, a pen-and-paper method.

A classi cation of plane and planar 2 - trees 1
We present new functional equations for the species of plane and of planar in the sense of Harary and Palmer, 1973 2-trees and some associated pointed species. We then deduce the explicit molecular expansion of these species, i.e.a classiication of their structures according to their stabilizers. Therein result explicit formulas in terms of Catalan numbers for their associated generating series...

متن کاملA zero one programming model for RNA structures with arclength ≥ 4
In this paper, we consider RNA structures with arc-length 4 . First, we represent these structures as matrix models and zero-one linearprogramming problems. Then, we obtain an optimal solution for this problemusing an implicit enumeration method. The optimal solution corresponds toan RNA structure with the maximum number of hydrogen bonds.
متن کاملType-Itemized Enumeration of RS-Stereoisomers of Octahedral Complexes
Stereoisograms of octahedral complexes are classified into five types (type I--typeV) under the action of the corresponding RS-stereoisomeric group. Their enumeration is accomplished in a type-itemized fashion, where Fujita's proligand method developed originally for combinatorial enumeration under point groups (S. Fujita, Theor. Chem. Acc., 113, 73--79 (2005)) is extended to meet the requireme...
متن کاملHalf-Century Journey from Synthetic Organic Chemistry to Mathematical Stereochemistry through Chemoinformatics
My half-century journey started from synthetic organic chemistry. During the first stage of my journey, my interest in stereochemistry was initiated through the investigation on the participation of steric effects in reactive intermediates, cylophanes, strained heterocycles, and organic compounds for photography. In chemoinformatics as the next stage of the journey, I proposed the concept of im...
