The vast majority of organic molecules (based on a carbon structure) are not flat, but have a three-dimensional geometry. Various results can be obtained depending on the way the atoms are arranged ...

In the search for new materials to be used in space environments, researchers are focusing on the crystallization of substances. By accurately observing and understanding the crystallization process ...

The properties of equivalent orbitals, as defined in previous parts, are examined in more detail. It is shown that the character of an equivalent set can be deduced knowing the symmetry group of a ...
