The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

(Nanowerk News) Ultrashort laser pulses in the femtosecond range have proven to be effective tools in driving photochemical reactions: under the influence of light, electrons change their energy ...

Yokohama, Japan - YNU researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C 2, Si 2, and their hydrides ...

Electron motions induced by a strong electric field are mapped in space and time with the help of femtosecond x-ray pulses. An x-ray movie of the crystal lithium hydride shows that the electric ...

A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic forces ...

A Dutch-German team of scientists has succeeded for the first time in controlling a chemical reaction via steering the motion of electrons with ultrashort laser pulses of a precisely controlled ...

"SOMETIMES IT SEEMS to me that a bond between two atoms has become so real, so tangible, so friendly, that I can almost see it. Then I awake with a little shock, for a chemical bond is not a real ...
