To understand how

interatomic distance affects intensity, microscopists plot a transfer function for the lens, which describes how specimen spatial frequencies are converted to an image from low frequencies (long distances) to high frequencies (short distances).

where f is a scaling factor, w is the characteristic atomic properties of the atoms i and j, [r.sub.ij] is the

interatomic distance between the ith and jth atom, and A is the number of atoms.

EXAFS fitting was carried out using the IFEFFIT library [27] within the ATHENA XAS data processing suite [28], and

interatomic distance estimates were obtained from the ATHENA suite [29].

For such packing each surface atom is surrounded by 6 other atoms on

interatomic distance of 278 pm (see Figure 1).

where [rho] is the distance between two well-defined distinct molecules, A = 4[epsilon][[sigma].sup.6] and B = 4[epsilon][[sigma].sup.12] denote the attractive and the repulsive constants, respectively, and [sigma] is the

interatomic distance when the potential is zero and [epsilon] is the energy well depth.

It is assumed that the high catalytic activity of the tin oxide-supported Pt is caused by the Pt-Sn bonds, which shortened the Pt-Pt

interatomic distance. As shown in Fig.

Meanwhile the

interatomic distance for C8-N2, N1-N2, N1-C1, and C1-O1 in the azomethine group (-C=N-N=C-O) moiety is 1.294,1.403, 1.317, and 1.278 A, respectively.

where [C.sub.6] is the dispersion coefficient for the pair of atoms, R is the

interatomic distance between atoms, and [E.sub.Disp] is the empirical term.

Moreover, the oxygen atom of carboxyl group of His162 also makes a strong H- bond with amide group of Gly165 with a 2.791 A distance which stabilizes the nucleophilic elbow.Further the Gln164 also assumes such a position that its amide group becomes placed in front of amide group of Leu75 belonging to Beta5 loop with an

interatomic distance of 4 A .

Therefore, the application of pressure which changes

interatomic distance of the substances changes its physical properties.

[7] created a geometrical hashing using

interatomic distance to identify the triples of atoms.
