Exemplary SRSim geometry: On the left, a molecule m
with two components c
, given in polar coordinates, is depicted. The angle θ can be imagined as descending from an imaginary polar component , while φ rotates the component in the equatorial plane from the imaginary zero-meridian φ0. The lengths from the center are given with d
. The angle α that is not specified but calculated from the polar coordinates is the effective angle between the components j and k. Three molecules and two bonds are shown on the right side. Because the middle molecule is connected with two other molecules (thick red arrows), the angle α would be realized under ideal conditions.
