Analyzing and Fitting NMR FID Signals with Python and SciPy

Analyzing Free Induction Decay (FID) signals is a fundamental step in processing Nuclear Magnetic Resonance (NMR) data, yet translating raw physical signals into accurate mathematical parameters can be challenging. This course guides you through the process of modeling and fitting scientific data using modern Python libraries. You will transition from understanding the core physics of FID signals to writing clean, structured Python code that extracts precise parameters like amplitude, frequency, phase, and relaxation times. By the end of this course, you will have developed a solid foundation in scientific computing workflows that you can apply to various data fitting challenges. What you'll learn: - Understand the mathematical and physical foundations of Free Induction Decay (FID) signals. - Apply NumPy and SciPy to preprocess and prepare raw scientific data for analysis. - Implement non-linear least-squares curve fitting algorithms to extract precise signal parameters. - Write structured Python code utilizing modern type hints and clean programming practices. - Analyze fitting errors and estimate parameter uncertainties to ensure scientific accuracy. - Practice modeling complex multi-exponential decay patterns through step-by-step written exercises. The course begins with essential signal processing terminology and mathematical definitions before moving into hands-on coding. You will progress through practical scenarios, starting with simple simulated signals and advancing to realistic, noisy data. This course is designed for students, researchers, and developers who are new to scientific computing in Python, with no advanced prerequisites required.
