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  within the ATHENA XAS data processing suite , and interatomic distance
estimates were obtained from the ATHENA suite .
Caption: Figure 2: Cs-corrected scanning electron microscope: (a) LiNb[O.sub.3] lattice with no RHT; (b) LiNb[O.sub.3] lattice after the RHT; (c) interatomic distance

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.
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.
 created a geometrical hashing using interatomic distance
to identify the triples of atoms.
