| Le Bel-van't Hoff rule | The number of stereoisomers of an organic compound is 2n where n represents the number of asymmetric carbon atoms (unless there is an internal plane of symmetry). A corollary of their simultaneously announced conclusions, in 1874, that the most probable orientation of the bonds of a carbon atom linked to four groups or atoms is toward the apexes of a tetrahedron, and that this accounted for all then-known phenomena of molecular asymmetry (which involved a carbon atom bearing four different atoms or groups). See: stereoisomerism. (05 Mar 2000) |

| rule of thirds |
This is the basic principle that is the most valuable to a new photographer. This rule takes our rectangular shape and divides it into thirds. The key elements or objects in a composition should fall on one of these thirds lines. The one point on our photograph where the viewers' eye comes to rest should fall on one of these lines where both a horizontal and a vertical line come to rest.
