Molecular motion pictures

Article Abstract:

The principles of high-speed photography are transferred to two-dimensional infrared spectroscopy in order to watch the motion of biological molecules in real time. Two-dimensional infrared spectroscopy is limited to studying certain types of oscillator in proteins because only a narrow range of oscillation frequencies is visible using this method.

Theoretical chemistry: The six-bond bound

Article Abstract:

The transition-metal dimers of chromium, molybdenum and tungsten are investigated in order to find the molecules with the highest effective bond order. The results have shown that six is the limit as far as covalent bonds between equal atoms are concerned.
