Fundamentals of Time Domain NMR (TD-NMR) and Data Processing

This course covers the theoretical and practical fundamentals of Time Domain Nuclear Magnetic Resonance (TD-NMR), a widely used technique for fast, non destructive, and sensitive analysis of material properties. Topics include nuclear spin behavior in magnetic

fields, relaxation mechanisms, and signal acquisition (FID, CPMG, IR, Spin Echo, MSE), as well as an overview of low field instrumentation and its differences from high field systems Key experimental parameters, such as T₁ and T₂ relaxation times, pulse sequences, and data acquisition strategies, will be discussed, along with fundamental approaches to data processing and interpretation, including Inverse Laplace Transform (ILT) and fitting methods. The objective of the course is to enable participants to understand TD-NMR principles, select appropriate methods, process data, and interpret results for research and practical applications.
