The best average values for C C bond lengths and C C C bond angles were calculated for fragments in which the C C bond was at least one C C bond distant from heavy atom substituents by using the results of searches of the Cambridge Structural Database. The values found, 1.51 Å and...
It has been observed that one-bond 13C 13C coupling constants are almost invariant with C C bond angles between tetrahedral and 127° for hydrocarbons where the central atom is a CH 2 group. An empirical quadratic equation is obtained which relates 1J CC with the internuclear C C C angle...
The last paragraph curses the universe thus unredeemed. The eleven initial A’s in the last sentence are Magick Pentagrams, emphasising this curse. NOTE (15) In nature the Tortoise has 6 members at angles of 60°. [63] 27Κ
