Synthetic molecular motors
Article Abstract:
Two new unrelated studies have moved chemists nearer to their goal of designing and synthesising molecular actuators that can change shape in response to stimuli, thereby, in principal, performing mechanical work. One design is based on a previous attempt to build a molecular ratchet and has produced a unidirectional, chemically driven system, which relies on chirality to define the direction of rotation. The second design is an alkene molecule that continuously rotates in the presence of ultraviolet light.

Hyperconjugation not steric repulsion leads to the staggered structure of ethane
Article Abstract:
Research examining steric effects as the cause of molecules preferred staggered conformations with application to ethane is presented. Particular attention is given to reactions of stabilization of the staggered structures through weakening of the C-C bond and hyperconjugation.

A new twist on molecular shape
Article Abstract:
Research examining the causes of shape complexity in molecules is presented. Particular attention is given to the forces responsible for internal rotations of molecules. Descriptions of the functionality of the forces determining shape changes in molecules are presented.
