The structural origin of absorption and fluorescence anisotropy of the single crystal of the π-conjugated heterocyclic system 5,6,10b-triazaacephenanthrylene, TAAP, is presented in this study. X-ray analysis shows that the crystal framework in the s

An elegant, well-established effective data filter concept, proposed originally by Abraham Savitzky and Marcel J.E. Golay, is undoubtedly a very effective tool, however not free from limitations and drawbacks. Despite the latter, over the years it ha

Graphical abstract In spite of a rapid growth of data processing software, that has allowed for a huge advancement in many fields of chemistry, some research issues still remain problematic. A standard example of a troublesome challenge is the analys

In this research, the occurrence and anomalous increase of an additional absorption band observed in the spectrum of fumaronitrile dissolved in toluene are explained and characterized. The formation of a stable ground-state complex between these two

In this paper, the nature of interactions between two cyanocarbons—tetracyanoethylene (TCNE) and fumaronitrile (FN)—and a series of four secondary amines possessing a general formula C4HxN (x = 5–11) is thoroughly scrutinized. For all of the TC

Spectra measured in various ranges of temperature are usually slightly different from each other in shape and position of the bands. Although the displayed inconsistencies are rather small, yet may lead to incorrect analysis and interpretation of the

The article presents a new algorithm for resolving the fluorescence spectra of three-component systems. The proposed method refers to a technique already known in the literature combining self-modeling based on singular value decomposition with numer

'White' and 'grey' methods of data modeling have been employed to resolve the heterogeneous fluorescence from a fluorophore mixture of 9-cyanoanthracene (CNA), 10-chloro-9-cyanoanthracene (ClCNA) and 9,10-dicyanoanthracene (DCNA) into component indiv

This is in response to Catalan's objection to our use of isopolarizability conditions in the resolution of the absorption and fluorescence spectra of the s-cis and s-trans all- trans -1.6-diphenyl-1,3,5-hexatriene ( ttt -DPH) conformers and the resol
