8 What most of us want i
9 It is easy
10 Introduction The Trinity of NMR (or a combination of) Integra tion Chemic al Shift Coupli ng
11 Phasing, Baseline correction (and lies) Will influence: Integration Chemical Shift Need to: Learn to appreciate their impact Know your algorithms
12 Pre-Acquisiton Considerations O O Expansion of aromatic region d1 = 0 sec d1 = 1 sec d1 = 3 sec d1 = 10 sec OH 37 % error (on signal at 7.8 ppm) 29 % error (Standard 1H) 17 % error 3 % error (Proton_Quantitative )
13 Phasing Strategies No perfect automatic solution But. Play!
14 Phase correction: Let s look at some integrals ph0 +3
15 Baseline Correction Considerations Influence over quantitation Multiple Choices Smooth: Polynomial Methods Aggressive: Smoothers, Splines Manual: slower but more precise
16 Baseline correction Whittaker: Influence on integrals
17 Referencing: Absolute Referencing Influence over chemical shift Consistency IUPAC recommendation: unified scale Added benefit: Alignment across all experiments
18 Absolute Referencing in Mnova For all nuclei: Manage References:
19 Peak Picking Different Approaches Standard Global Spectral Deconvolution Effect over: Chemical Shift Coupling
20 Standard Peak Picking Simple algorithm: Look for peak maxima Good enough for certain cases But. Peak overlap Insufficient peak resolution Not accurate coupling constants
21 GSD Intro Multiplication of the FID by a resolution-enhancement function But: poorer SNR and peak shape distortions
22 GSD Intro Resolution Booster Original Integral part of GSD
23 Why GSD (overlap) Overlap
24 Why GSD (Auto-classification of peaks)
25 Why GSD - Couplings
26 But why?! Because we can reconstruct the data
27 To the report! Now that some of you are scared Creation of reporting templates, including: Exact look and feel All the analysis operations (phase and baseline correction, peak picking, autoclassification, reports of multiplets and parameters )

33 Verification and Prediction Areas y Methodologies Manufacturing Development Research Mnova MS Databases SMA qnmr Verification and Prediction NMR: Functionality
34 Verification and Prediction Approaches 1 H NMR Increments (Prof Erno Prest) Conformers (Prof Ray Abraham) Access through:
35 Verification and Prediction Approaches 13 C NMR HOSE Code Wolfgang Robien Neural Networks Wolfgang Robien
36 1 H NMR Prediction Increments Similar (but different to HOSE) Uses substructures Very accurate Easy to anonymize Over 10,000 structurally different molecules in the DB Data organised into multiple databases
37 1 H NMR Prediction Conformers Semi empirical approach Takes into consideration the 3D structure of the compound Thousands of compounds used to create the models Effective when dealing with flexible systems Visualise the conformers that contribute to the predictions
38 13 C Prediction 13 C HOSE Concept of Shells : how similar are the substructures as we go further away from the Carbon atom predicted: 5 shells: perfectly represented 1 shell: not represented Over compounds in the prediction database Constantly updated
39 13 C Prediction 13 C Neural Networks Fall-back approach More accurate than any other when no representative data can be found in the database
40 Method Selection Best Approach and Error Estimation Algorithm to decide which model produces the best predictions Errors calculated following considerable atom by atom type analysis
41 Solvents Solvents For 1 H NMR three solvents are considered by default: CDCl 3 DMSO D 2 O For 13 C NMR the solvent is automatically detected and the predictions are produced from relevant data.
42 Error interpretation Error Interpretation It is possible for any given prediction to display the estimated errors of the prediction graphically or in a table format:
43 Results Result Overview The inclusion of user data has a marked effect: Total refers to the effect over the entire of the dataset, Partial only for those atom that showed a change Total Partial Total Partial 13C 13C 1H 1H Improvement %
44 Structural Determination Need workflows to Track information across multiple Record these effectively But need the killer experiment

60 Verification and Prediction Areas y Methodologies Manufacturing Development Research Mnova MS Databases SMA qnmr Verification and Prediction NMR: Functionality
61 Methodologies Internal Reference External reference Artificial Signal Conversion Factor 2D Methods Relative Response Factors
62 qnmr qnmr: General aspects of data processing Sample preparation, shimming, temperature stability Interpulse delay Signal-to-noise-ratio (SNR)(guideline: 150) Number of data points/peak Apodisation Phase correction Baseline correction Integration method Integration regions Blind regions
63 qnmr Basics of qnmr spectroscopy Fundamental relationship of qnmr: the signal intensity in the NMR spectrum is directly proportional to the number of nuclei responsible for that particular resonance (1) so I I X X = N K X S N X where K S is the spectrometer constant and remains the same for all the resonances in a NMR spectrum Relative quantitation method The easiest method where the molar ratio between two compounds (M x /M y ) can be calculated M M X X ( 2) = Y I N X N I Y Y Absolute quantitation method and Purity By determining the absolute concentration of an analyte it is possible to derive its purity: I. If all the impurities (or other components) present in the NMR spectrum can be measured quantitatively, then the assay is just a difference from the 100% value II. Otherwise purity of a compound X is derived by the comparison with a standard according to the formula: I N MW X STD X ( 3) PX = ISTD NX MWSTD W W STD P STD where, I, N, M, W and P are integral area, number of nuclei, molar mass, gravimetric weight and purity of analyte (X) and standard (STD), respectively 63

76 SMA You can design an SMA experiment to: Search for a multiplet or integrate a spectral region Use of GSD in areas of peak overlap Peak pattern recognition SMA will automatically determine these areas for each spectrum Specify an equationthat converts that area into meaningful quantification If necessary, use an internal quantitation standard / 76

79 SMA basics Further flexibility in equation usage Factorise partly hidden, or semi-saturated signals 1D or 2D Specify the NMR experiment for a sample mix and match Use a previous result in a later equation 79
80 Extending targeted analysis Multiple spectral information for a sample Extends the scope of targeted analysis 80
