Stochastic Dynamics Hard- and Soft-Ionization Mass Spectrometry
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 introduct...
Quantification by Matrix-Assisted Laser Desorption Ionization Mass Spectrometry Using An Approach Based On Stochastic Dynamics. Experimental And Theoretical Correspondences
Research Paper (postgraduate) from the year 2018 in the subject Chemistry - Analytical Chemistry, grade: Mass spectrometry, University of Dortmund (Institut für Umweltforschung, Lehrstuhl für Analytische Chemie), language: English, abstract: The goal of this work is to describe more recent developments in the quantitative mass spectrometry and to illustrate how our new model equations based on the stochastic dynamics relate to the determining the 3D molecular and electronic structures of analytes. It is aimed at researchers in Chemistry who would like to find out about what is going on in mass spectrometric methodological contributions more recently. The work could also be used to MSc and PhD students in the field of Chemistry, in particular, highlighting the ‘Analytical chemistry’, ‘Physico–chemistry’ and/or ‘Computational and theoretical chemistry’, respectively.
Electrospray Ionization and Collision Induced Dissociation Mass Spectrometric Quantitative Conjunctions with the Experimental Intensity of the Analyte Ions of Metal–Organics – Stochastic Dynamics
Research Paper (postgraduate) from the year 2019 in the subject Chemistry - Analytical Chemistry, University of Dortmund (Institute of Environmental Research, Department of Analytical Chemistry), language: English, abstract: Throughout the chapters in this book we argue that the temporal behaviour of the experimental mass spectrometric intensity of analyte ions obeys a certain and universal law based on a stochastic dynamic approach. The content of the book evidences convincingly through a selected series of examples to molecular systems of metal–organic complexes of transition metal ions with electronic configuration d10, for instance, AgI– and ZnII–ions, the validity of our model equ...
Linearly Polarized IR Spectroscopy
A technique that is useful in the study of pharmaceutical products and biological molecules, polarization IR spectroscopy has undergone continuous development since it first emerged almost 100 years ago. Capturing the state of the science as it exists today, Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis demonstrates how the technique can be properly utilized to obtain important information about the structure and spectral properties of oriented compounds. The book starts with the theoretical basis of linear-dichroic infrared (IR-LD) spectroscopy and then moves on to examine the background of the orientation method of colloid suspensions in a nematic host...
On the temperature dependence on the stochastic dynamic mass spectrometric diffusion parameter
Research Paper (postgraduate) from the year 2019 in the subject Chemistry - Analytical Chemistry, University of Dortmund (Institut für Umweltforschung), language: English, abstract: The major aim of this work is to introduce our new model equation connecting among the so–called stochastic dynamic diffusion coefficient “DSD,” the experimental mass spectrometric outcome intensity “I” and the experimental parameter temperature “T,” respectively. A closer review of our contributions, so far, to the domain of the “stochastic dynamic mass spectrometry” has shown that we have developed a functional relationship between the DSD parameter and the mass spectrometric intensity. It is...
Quantitative Relations Among Temperature, Analyte Concentration in Solution, Stochastic Dynamic Diffusions and Mass Spectometric Variable Intensity
Academic Paper from the year 2020 in the subject Chemistry - Analytical Chemistry, grade: Second author Michael Spiteller, University of Dortmund (Institut für Umweltforschung), language: English, abstract: The idea for this contribution has its root in exact formulas connecting between measurable variable intensity of mass spectrometric peak of analyte ion and its stochastic dynamic diffusion parameter introduced, more recently in our works devoted to quantitative mass spectrometry. Herein, we present innovative functional relations connecting among not only DSD- and I-parameters, but also the experimental factor temperature and the concentration of analyte in solution. The temperature is ...
The Crystallographic Polymorphism of Pharmaceutics. A Quantum Chemical and Chemometric Treatment
Academic Paper from the year 2021 in the subject Chemistry - Analytical Chemistry, University of Dortmund (Institute of Environmental Research), language: English, abstract: In this work we discuss certain consideration for quantum chemical and chemometric assessing in the crystallographic polymorphism. It is aimed primarily at researchers in ‘Analytical chemistry’ and is designed to help readers’ understanding of the implications of the different quantum chemical theories in the chemical crystallography. The term ‘polymorphism’ reflects molecular ability to crystalize in more than one structure. Since, properties of polymorphs can vary, their quantification becomes an important ta...
Mass spectrometric study of randomly acetylated cyclodextrins and their associates. A stochastic dynamic approach
Academic Paper from the year 2020 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, grade: Excellent, TU Dortmund (Institut für Umweltforschung), course: Forschungsstipendium, language: English, abstract: A work on nonsubstituted cyclodextrins does illustrate persuasively the applicability of our innovative stochastic dynamic formulas connecting among measurable outcome intensity, analyte concentration in solution, the temperature and molecular properties to quantify and determine 3D structurally analytes. They bridge the gap between theory and experiment, in developing highly selective, sensitive, accurate and precise methods for quantification and exact 3D structural analytes by mass spectrometry.

Molecular structure and properties of silver (I/II/III) containing organometallics
Research Paper (postgraduate) from the year 2011 in the subject Chemistry - Anorganic Chemistry, TU Dortmund (Fakultät für Chemie und Chemische Biologie, Institut für Umweltforschung, Lehrstuhl für analytische chemie), language: English, abstract: Despite a tremendous number of books, monographs, textbooks and review-articles devoted to “organometallic chemistry”, the largest part of those contributions have been designed into following structure of the content: (i) Manuals, handbooks and encyclopedias summarizing important organometallic reagents in the organic synthesis; (ii) Books, containing synthetic protocols for obtaining of organometallic reagents; and (iii) Manuals on basic ...
