It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The IR spectrum of polyimide films produced on the basis of Hydroxy-4, 4-dianiline and lacquer ABimida was measured. The carried out quantum-chemical calculations of the spectra within the Hartree-Fock approximation MDDP PM3 on the model material (a copolymer of dianhydridethreecyclodetsentetra carboxylic acid and diaminodiphenyl ether) show that the bulk of experimental and theoretically calculated bands in the frequency range 2000 - 400 cm-1 is identical.
