About this course

Nuclear magnetic resonance spectroscopy or NMR spectroscopy is the most informative analytical method for studying the structure of organic molecules, and is also used for their direct quantitative determination even in complex mixtures. Therefore, it is widely used for identification and quantification of biologically active substances, auxiliary substances and impurities in pharmaceutical analysis. NMR spectroscopy combines a unique set of advantages: simple sample preparation, rapidity, universality, precision, the possibility of relative and absolute quantitative determination of components without authentic reference compounds. In addition, NMR spectroscopy is a non-destructive method, and after recording the NMR spectrum, the analyte can be analyzed by other methods.

Who is this course for?

The course is primarily addressed to students studying in the specialties “Pharmacy” and “Chemistry”, as well as specialists with higher education, working in pharmaceutical and chemical field.

What do I need to know?

It is necessary to know the basics of organic, analytical chemistry and also to be able to work with information sources.

What will you have learnt?

By the end of the course you will know: theoretical basis of ¹H NMR spectroscopy; the relationship of the ¹H NMR spectra parameters with the structure of molecules; identification of molecules using ¹H NMR spectra; the effect of physico-chemical properties on quantitative analysis; possibilities of ¹H NMR spectroscopy in the quantitative analysis of simple and complex organic systems; rules for the creation and validation of quantitative ¹H NMR spectroscopy techniques.
