H2+: the molecule of molecules
Physics World, 1995The articles on the many different forms of hydrogen in July's Physics World were fascinating, but there was one glaring omission – the molecular ion, H2+. What prevented this simple, friendly little molecule from appearing amongst its relatives?

We studied complexity of several classes of molecular graphs: linear and branch trees, (poly)cycles and general graphs. Trees and (poly)cycles are simple graphs that are graphs without multiple edges and loops. General graphs are graphs with multiple edges and loops. A loop is an edge with both of its vertices identical.

Table 10.1 gives some approximate values for the atomic composition of a cell. The atomic composition represents a highly reductionist view, somewhat akin to asserting that the informational content of Macbeth is — Σaipnabec p i 1og2p i , where p i is the normalized frequency of occurrence of the ith letter of the alphabet. The next stage of complexity

Carbon monoxide molecules were arranged in atomically precise configurations, which we call “molecule cascades,” where the motion of one molecule causes the subsequent motion of another, and so on in a cascade of motion similar to a row of toppling dominoes.

Faraday Discuss., 2007
Chemistry is determined by the electrostatic forces acting within a collection of nuclei and electrons. The attraction of the nuclei for the electrons is the only attractive force in a molecule and is the force responsible for the bonding between atoms. This is the attractive force acting on the electrons in the Ehrenfest force and on the nuclei in the

Measurements of vapor pressures over their aqueous solutions indicate that organic compounds show profound differences in hydrophilic character. These differences are of such magnitude as to suggest an important role for changing solvation in determining free energy changes associated with metabolic transformations in water, and in governing structural

Experimental Investigations of Molecule-Molecule and Electron-Molecule Scattering
1975Part I. Crossed molecular beam methods have been used to measure the differential elastic scattering of molecular hydrogen and deuterium with a number of diatomic and polyatomic secondary molecules. In particular, H2 + O2, SF6, NH3, H2O, CO and CH4 and D2 + O2, SF6, NH3, and H2O were all studied using thermal energy beams.
