27 After the shielding tensor field was obtained, the average anisotropy of the chemical shielding induced by the cage was obtained as follows: the spatial volume accessible to the hydrogen molecule inside the fullerene cage was estimated by taking the difference between the geometrical volume of the cage and the union of the carbon atom spheres with an assigned van der Waals radius of 1.70 Å.
A straightforward calculation of the derivative of Q gives the capacitance of the charged particle with 338 electrons C=6.1×10-22 F that is much lower than C=1.1×10-17 F of the neutral 336-atom sphere.
The technology (first reported in DeSutter & Stieff, 2014) belongs to a class of molecular visualization interfaces (e.g., Jmol, PyMOL, Avogadro) that use molecular structure data files to depict complex molecules as a visual representation of atoms (spheres) connected via single, double, or triple bonds (cylinders).
Because the relevant pocket is relatively small, a spatial point constraint with a tolerance of 0.75 Å was added to the carbon atom (magenta sphere, Figure 1 B D).
Shown are the 13 active-site residues conserved in all EEVS enzymes (pale purple carbons), the NAD+ (gray carbons), and the Zn2+ atom (silver sphere with black coordination bonds), along with a mesh that delineates the pocket suitable for binding an SH7P substrate.
If scientists can nail down the mass of the silicon atom, the spheres would translate that mass to the macroscopic scale.
It can be seen that the side Zn atom (green spheres) at the ZnO branch is covalently bonded to three extra O atoms with single bond (denoted by dashed circle).
(2) It was hypothesized that a large overlap of information occurs between Alpha HB Scoring (C) and ASE Scoring (A) on account that the same content on ligand atom-alpha sphere pairs was used to evaluate the energy.
Dalton had pictured atoms as spheres and compound atoms as characteristic arrangements of spheres.
A) The required locations for hydrogen bond-donating atoms (blue-dotted spheres) and a hydrogen bond-accepting atom (red-dotted sphere) in the hinge region.
For his movies Berry has the choice of how best to render the resulting structures – with individual atoms as spheres, or perhaps just displaying the molecular surfaces – and to colour them to enhance distinctions between different molecular parts and players (in reality, most proteins are rather colourless).
