71Fermionic condensate — A fermionic condensate is a superfluid phase formed by fermionic particles at low temperatures. It is closely related to the Bose–Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions. Unlike the Bose–Einstein… …
72Structural alignment — is a form of sequence alignment based on comparison of shape. These alignments attempt to establish equivalences between two or more polymer structures based on their shape and three dimensional conformation. This process is usually applied to… …

74Cubic crystal system — A rock containing three crystals of pyrite (FeS2). The crystal structure of pyrite is simple cubic, and this is reflected in the cubic symmetry of its natural crystal facets …
75Amorphous carbon — is an allotrope of carbon that does not have any crystalline structure. As with all glassy materials, some short range order can be observed, but there is no long range pattern of atomic positions. Amorphous carbon is often abbreviated to aC for… …

77Rigid rotor — The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3 dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the… …
78Phase problem — The phase problem is the name given to the problem of loss of information (the phase) from a physical measurement. The name itself comes from the field of x ray crystallography, where the phase problem has to be solved for the determination of a… …
