Formula Periodic Tables-Their Construction and Related Symmetries
The algorithmic construction of formula periodic tables for polycyclic conjugated hydrocarbons is detailed. The symmetries associated with this construction are identified. The formula periodic table for benzenoids (Table PAH6) exhibits a one-to-one mapping onto the formula periodic table for fluorenoids/fluoranthenoids minus the constant-isomer fluorenoid/fluoranthenoid formulas and the formul...
متن کاملPartitioned-Formula Periodic Tables for Diamond Hydrocarbons (Diamondoids)
Isomeric diamond hydrocarbons (diamondoids or polymantanes) with the same number n of adamantane units share the same molecular formula C(Q)(CH)(T)(CH(2))(S) and can be divided into valence isomers (denoted as Q-T-S) by partitioning the number C = Q + T + S of their carbon atoms according to whether they are quaternary, tertiary, or secondary. Vertices of dualists are the centers of adamantane ...

In several problems considered in the Antenna Laboratory, Cambridge, Mass., the functions fi(x) = x tan * and/2(ac) = x tanh x have arisen. Tables of these functions with the required range, interval of argument, and number of significant figures apparently do not exist; consequently, such tables were computed specifically to satisfy these needs. They were prepared in the form of reports with t...
متن کاملOn the Mark and Markaracter Tables of Finite Groups
Let G be a finite group and C(G) be the family of representative conjugacy classes of subgroups of G. The matrix whose H,K-entry is the number of fixed points of the set G/K under the action of H is called the table of marks of G where H,K run through all elements in C(G). Shinsaku Fujita for the first time introduced the term “markaracter” to discuss marks for permutation representati...
