Principle of structure correlation

More generally, the relationship of structure correlations to features of the energy surface is expressed in the principle of structure correlation [16a] ... 

The answer to the question of how an efficient metabolism can be maintained in the presence of low concentrations of intermediary substrates is found in what may be called the principle of spatial correlation. This principle explains how permanent biological structures may have originated in evolution from the dynamic spatial order described by Pri-gogine. 

In addition to examples quoted in Section II,C, the CD spectra of the following compounds have been recorded hemandezine, isotetrandrine, thalsimine, thalsimidine, 0-methylthalicberine, thalisopine, thalisopidine, thalmine, thal-fine, three related derivatives, and two unidentified bases isomeric to thalbaden-sine. Spectra were measured in neutral MeOH, as well as after addition of HC1. Several general principles of structural-spectral correlation were deduced (141).

In contrast to IR and NMR spectroscopy, the principle of mass spectrometry (MS) is based on decomposition and reactions of organic molecules on theii way from the ion source to the detector. Consequently, structure-MS correlation is basically a matter of relating reactions to the signals in a mass spectrum. The chemical structure information contained in mass spectra is difficult to extract because of the complicated relationships between MS data and chemical structures. The aim of spectra evaluation can be either the identification of a compound or the interpretation of spectral data in order to elucidate the chemical structure [78-80],... 

This assay system developed by Chaires [136] is a new, powerful and effective tool based on the fundamental thermodynamic principle of equilibrium dialysis for the discovery of ligands that bind to nucleic acids with structural and sequence selectivity. Here, identical concentrations of various nucleic acid samples are dialysed in dispodialysers against a common ligand solution. At equilibrium, the contents of the ligand bound to each nucleic acid are determined and this is correlated directly to the ligand s specificity to a particular sequence.
