Research Paper (postgraduate) from the year 2023 in the subject Chemistry - Analytical Chemistry, TU Dortmund (Institute of Environmental Research), language: English, abstract: The contribution brings together our most recent papers, dealing with stochastic dynamics mass spectrometry, the first of which is written specially for this book. It can be regarded as introductory review-chapter, which represents, in fact, an overview of contributions devoted to methodological development of quantitative and structural stochastic dynamics mass spectrometric approaches to soft-ionization methods.The books are primarily intended for widespread use of graduated students, who after the first introductory Chapter 1 to the field of stochastic dynamics soft-ionization quantitative and 3D structural mass spectrometry may wish to deepen their knowledge of primary application of model formulas to hard-ionization approaches. Of course, we hope that it shall be useful not only to undergraduate student, but also to both junior and senior academics and researchers in the analytical mass spectrometry. Owing to the fact, that analytical mass spectrometry is robust method for quantitative and structural analysis, amongst others, not only for fundamental science and a lot of specific scientific disciplines, but also to the industry, the book is designed to serve major and specific goals of both science and various branches of the industry.

The reader to whom the author¿s contribution has addressed should be recognized with more recent debate on the capability of the linear polarized spectroscopy to elicit accurate structural information about the molecules in the solid¿state. The content is directly related to linear polarized infrared (IRLD) spectroscopy of colloidal suspensions in nematic liquid crystals. The author has presented the formalism of the söcalled ¿reducing difference method¿ (RDM) and its applicability to quantitative treatment of IRLD spectra. The work contains a theoretical description of the aforementioned methodology together with statistically representative experimental evidences, according to the author, consisting of quantitative analysis of polarized IRLD spectra in solid¿state ¿ in total 45 polarized IR spectra of 5 analytes ¿ on the base on RDM. Chemometrics is presented, as well. The correlative analysis between theory and experiment has been documented. The empirical testability of the ¿reducing difference method¿ and the credibility of the IRLD structural analysis based on the RDM have been detailed.

Czytelnik, do którego skierowano uwagi autora, zas¿uguje na uznanie dzi¿ki niedawnej debacie na temat zdolno¿ci liniowej spektroskopii spolaryzowanej do uzyskiwania dok¿adnych informacji strukturalnych o cz¿steczkach w stanie stäym. Zawarto¿¿ ta jest bezpo¿rednio zwi¿zana ze spektroskopi¿ w liniowej spolaryzowanej podczerwieni (IRLD) koloidalnych zawiesin w ciek¿ych krysztäach nematycznych. Autor przedstawi¿ formalizm tzw. "metody ró¿nic redukcyjnych" (RDM) i jej zastosowanie do ilo¿ciowego traktowania widm IRLD. Praca zawiera teoretyczny opis powy¿szej metodyki wraz ze statystycznie reprezentatywnymi, zdaniem autora, dowodami do¿wiadczalnymi polegaj¿cymi na ilo¿ciowej analizie spolaryzowanych widm IRLD w stanie stäym - ¿¿cznie 45 spolaryzowanych widm IR 5 analitów - na podstawie RDM. Przedstawiono równie¿ chemometri¿. Udokumentowano analiz¿ korelacyjn¿ pomi¿dzy teori¿ a eksperymentem. Okre¿lono empiryczn¿ testowalno¿¿ "metody ró¿nic redukcyjnych" oraz wiarygodno¿¿ analizy strukturalnej IRLD opartej na RDM.
