This resource combines high-field magnets, modern spectrometers, and expert staff to deliver timely, high-quality data. The following sections summarize capabilities, access models, and practical operating information for current and prospective users.
| Facility Type | Core Service | Typical Users | Key Support |
|---|---|---|---|
| High-Field NMR | 1H, 13C, 15N, 31P, 2H spectroscopy | Academic researchers | Instrument training and scheduled access |
| Solid-State NMR | Magic-angle spinning, CP/MAS, relaxation | Materials scientists | Method development and data processing |
| Solution NMR | Protein structure, dynamics, metabolomics | Biochemists and structural biologists | Sample prep guidance and spectral interpretation |
| Method Development | Custom pulse sequences and temperature studies | Industrial partners | Project-specific consulting and training |
Access and Instrument Reservation
UCBerkeley NMR operates a shared-access model that allocates spectrometer time through core facilities and departmental committees. Priority is typically given to funded research, teaching requirements, and users with training certification.
Online booking systems display real-time availability, required sample qualifications, and estimated turnaround times. Users must complete facility orientation and method approval before scheduling their first experiment.
Instrumentation and Capabilities
The facility maintains a range of spectrometers with magnetic field strengths from 400 MHz to near 1 GHz, enabling both solution and solid-state measurements. Cryoprobe technology improves sensitivity for low-concentration samples and reduces data collection times.
Advanced capabilities include triple-resonance experiments, diffusion-ordered spectroscopy, and solid-state magic-angle spinning at high frequencies. Each instrument is regularly calibrated and maintained to ensure consistent spectral quality.
Method Development and Experiment Design
Staff scientists assist users in selecting optimal pulse sequences, solvents, and sample conditions for their target molecules. Early consultation helps avoid failed experiments and improves reproducibility across projects.
Custom parameter sets for temperature control, field gradients, and relaxation delay settings are available. Method development support is particularly valuable for complex biological macromolecules and sensitive materials.
Data Processing, Reporting, and Archiving
Raw spectral data are processed using standardized software pipelines, with options for phasing, baseline correction, and referencing to internal standards. Processed spectra are exported in open formats compatible with common analysis tools.
Detailed metadata, experimental parameters, and instrument logs are archived to support publication requirements and long-term reproducibility. Users receive concise summary reports alongside full technical raw data for their records.
Operational Recommendations and Best Practices
- Complete facility orientation and method approval before your first booking
- Verify solvent compatibility and sample stability at the desired temperature
- Provide detailed metadata for spectral processing and long-term archiving
- Schedule method development early for complex or novel experiments
- Maintain open communication with staff for timely troubleshooting and reporting
FAQ
Reader questions
How do I propose a new NMR experiment not listed in the standard methods?
Contact the method development team with details about your target molecule, detection nuclei, and acquisition goals. They will evaluate feasibility, estimate time requirements, and, if approved, add the method to the facility library.
What sample preparation rules apply to sensitive or hazardous compounds?
Use deuterated solvents at the recommended concentration, choose NMR-compatible tubes, and clearly label tube content and hazards. Submit any special handling instructions with the sample request form for prior approval.
Can industry collaborators access the facility under a proprietary confidentiality agreement?
Yes, after completing standard orientation and method approval, industry projects can proceed under a tailored confidentiality agreement that defines data-sharing and publication terms in advance.
How are spectrometer time allocations prioritized during high demand periods?
Prioritization follows a published schedule that weighs funding source, teaching obligations, and user training level. Large collaborative projects and multi-user experiments are scheduled to maximize overall facility utilization.
