A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...
Draw the structure in your molecule editor (ideally change the settings to give a molecule twice the size as the JACS standard or change the size to 200% before next step), and save it as an Encapsulated PostScript file (.eps) - many of the Apple print drivers (an Apple printer is not required) that print to a PostScript printer can be set to ...
Fixed length and fixed angle drawing; Automatic alignment of figures; Detection of structures, text, and arrows, and their automatic placement; Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in a built-in library; Retrieval of structures from a network database based on CAS number, formula, or ...
A two component diagram with components A and B in an "ideal" solution is shown. The construction of a liquid vapor phase diagram assumes an ideal liquid solution obeying Raoult's law and an ideal gas mixture obeying Dalton's law of partial pressure. A tie line from the liquid to the gas at constant pressure would indicate the two compositions ...
a solid solution mixes with others to form a new solution The phase diagram in the above diagram displays an alloy of two metals which forms a solid solution at all relative concentrations of the two species. In this case, the pure phase of each element is of the same crystal structure, and the similar properties of the two elements allow for ...
The individual atoms of the polypeptide have been hidden. All of the non-hydrogen atoms in the two ligands are shown near the top of the diagram. Ribbon diagrams are schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon shows the overall path and organization of the ...
The structures of many reagents are often misunderstood because simplified formulas are presented in reaction schemes whereas the actual structures are more complex. Examples are methyl lithium and lithium diisopropylamide. Readers of Wikipedia often comment (complain) that structures shown are incorrect for this reason.
Stiff diagrams can be used: 1) to help visualize ionically related waters from which a flow path can be determined, or; 2) if the flow path is known, to show how the ionic composition of a water body changes over space and/or time. Example of a Stiff diagram. A typical Stiff diagram is shown in the figure (right).
