Visuals for Basic NMR Training Workshop Lecture II
These visuals are made from the original lecture transparencies
NMR Data Processing - In General
Window Functions: Shaping the FID
Window Functions: Mathematical Multiplication
Effect of Various Multiplier Functions on the FID
Effect of Various Multiplier Functions on the Spectrum
Exponential Multiplication (EM): Signal-to-Noise and Peak Width
Example: Methyl m-Nitrobenzoate Resolution Enhancement
Window (Multiplier) Functions: Comparison on Real Data
Zero Filling - Getting More Data Points in the Spectrum
Digital Resolution: 3.0 Hz/pt. vs. 0.3 Hz/pt.
Phase Correction
Phase: Dispersive and Absorptive Peak Shapes
Phase Correction - How It Works
Phase Correction: Linear Combination of Real and Imaginary Spectra
Phase Correction with a Hypothetical Spectrum: Zero and First Order Terms
Example: Before Phase Correction
Example: After Zero Order Phase Correction
Example: After Partial First Order Phase Correction
Example: After Complete First Order Phase Correction
Phase Twist and How to Avoid It
Baseline Correction: Removing the Smile
Example: Before Baseline Correction
Example: After 5th Order Polynomial Baseline Correction
