The book is divided into three parts (Basics of CASE, Overview of CASE systems, and a comprehensive discussion of their own system, Structure Elucidator) comprised of overall 14 chapters.5/5(3).

Computer-Assisted Structure Elucidation (CASE) applications are widely used today to characterize chemical structures from both natural and synthetic products.

In the past decade, multiple reviews have been published to illustrate that ACD/Structure Elucidator Suite [] is capable of identifying the chemical structure of very complex molecules with the aid of NMR and MS information.

A set of 79 2 J CH and 3 J CH collected from a single HSQMBC experiment on a sample of strychnine were used in the CASE‐3D protocol (Computer‐Assisted 3D Structure Elucidation).

In addition to the most commonly used 3 J CH coupling constants, the subset of 32 2 J CH alone showed an excellent degree of configuration selection. There are still a disturbing number of incorrect natural product structure elucidations reported in the literature.

The use of Computer-Assisted Structure Elucidation (CASE) programs can minimize this risk by generating all structures that are consistent with the input data and by ranking these structures in order of by: 8. The Structure Elucidation Challenge Between anddifferent datasets were submitted from various industries as challenges to the ACD/Structure Elucidator Suite system.

[3] The structures determined ranged from to more than Da (Figure 5) and the software had excellent success determining the correct structures (Figure 6). Introduction. In its modern usage, the term computer-assisted structure elucidation (CASE) refers to the process where a software is applied to generate all possible molecular structures that are consistent with a particular set of NMR spectroscopic data, possibly complemented with the known or assumed elemental composition of the molecule.

Structure elucidation in this article is focused on databases, expert systems and modelling techniques based on different spectroscopic methods. Databases of spectroscopic data include information. Article Views are the COUNTER-compliant sum of full text article downloads since November (both PDF and HTML) across all institutions and individuals.

Computer-aided structure elucidation methodology is discussed. Major processes involved in computer-aided structure elucidation systems are partial-structure elucidation, structure generation, and structure examination.

For the three representative systems CONGEN, CASE, and CHEMICS, these processes are examined. The authors overall goal is writing this book is to produce the ‘must read’ definitive text that will represent the results of decades of work to develop computer-assisted structure elucidation.

Computer-Assisted Structure Elucidation (CASE) is comprised of two steps: 1) generation of all possible structural isomers for a given molecular formula and 2D NMR data (COSY, HSQC and HMBC), and. This book has three major sections that facilitate understanding the science, evolution of and workflows for Computer-Assisted Structure Elucidation as applied to molecular structures.

Part I addresses the fundamental concepts and mathematical coding and processing of spectral molecular structure information into useful information concepts and matrices that can be used in structure elucidation.5/5.
