Motivation. Kohonen Self–Organizing Feature Map (SOM Kohonen map) is a technique used for pattern classification. The method can be applied to classify different classes of organic compounds based on 13 C NMR chemical shift data. This can be a very useful tool in structure validation, which is one of the steps of automated structure elucidation process. In(More)
The aim of this paper is to present a procedure that utilizes 13C NMR for identification of substituent groups which are bonded to carbon skeletons of natural products. For so much was developed a new version of the program MACRONO, that presents a database with 161 substituent types found in the most varied terpenoids. This new version was widely tested in(More)
