The mass analyzer contains a strong magnetic field, through which the molecular ions must pass.
He calls the method "click chemistry", because of the ease with which the molecular building-blocks fit together.
In a molecular structure the bond lengths and bond angles are those for which the molecular energy is the least.
Junctions that use a single molecule are more flexible in that the states in which the molecular switch conducts electricity can be "tuned".
While the above argument is to be considered only suggestive, Henry's law is found experimentally to hold for all dilute solutions in which the molecular species is the same in the solution as in the gas.
Cross-linked polymers, in which the molecular structure is a network, are thermosetting resins (i.e., they form under the influence of heat but, once formed, do not melt or soften upon reheating) that do not dissolve in solvents.
Zeolites are used as molecular sieves to remove water and other small molecules from mixtures, and they can also be employed to separate molecules for which the molecular masses are the same or similar but the molecular structures are different.
This happens in all cases in which the molecular diffusion mechanism is switched off.
The major elements and molecules of the solar nebula are shown in Table 1, in which the molecular abundances are calculated following Yamoto (2003).
The mass spectra gave an additional evidence for structure formation in which the molecular ion peak appeared at m/z 387 (M+-piperidyl, 2%%).
High-resolution three-dimensional structures of numerous isoenzymes are known from which the molecular details of catalysis can be inferred and tested with enzymological techniques.
