Chemical shifts and coupling
solution 1D and 2D NMR
Material Analysis · Structure & Spectroscopy
Characterise chemical shifts and coupling, molecular connectivity, local structure, and dynamics, and purity, composition, or quantitative ratios using a scope agreed around your sample and decision.
Why this service
Solid-State Nuclear Magnetic Resonance Spectroscopy is selected when the project needs defensible information on chemical shifts and coupling, molecular connectivity, local structure, and dynamics, or…

Common outputs
Fields, conditions, processing and file formats are confirmed before work begins.
Processed 1D/2D or solid-state spectra reported with the agreed units, sample reference and measurement conditions.
Peak assignments and integrals supplied in a labelled format suitable for direct sample or condition comparison.
Optional relaxation, diffusion, or quantitative analysis provided with the processing basis and quality checks agreed during technical review.
Processed spectra included when selected in the confirmed reporting scope.
Sample requirements
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Powder / particles | Provide a dry, homogeneous and clearly labelled sample in a sealed container. | Exact mass and any drying or dispersion step are confirmed after technical review. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Solid / component | Provide a clean, stable and clearly labelled specimen with the target face or region identified. | Confirm dimensions, cutting permission and whether the original geometry must be preserved. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Short answers to issues that can change preparation, scope, timing or interpretation.
Provide powder / particles, liquid / solution, solid / component as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Choose the mode around the decision you need to make. For chemical shifts and coupling, start with solution 1D and 2D NMR; add MAS solid-state NMR when comparison or quantification is required.
Typical turnaround is 7 working days after sample acceptance and method confirmation.
Low sensitivity, overlap, paramagnetism, and long experiments can constrain minor components. Structure assignment may require complementary MS or diffraction.
