Hadamard excitation sculpting

Area of Science:

• Nuclear Magnetic Resonance (NMR) Spectroscopy
• Quantum Information Science

Background:

• Excitation sculpting is a technique used in NMR to improve spectral resolution and selectivity.
• Performing selective experiments at multiple sites can be time-consuming.

Purpose of the Study:

• To present an approach for Hadamard phase encoding and editing in excitation sculpting experiments.
• To demonstrate the utility of Hadamard excitation sculpting (HEX sculpting) for reducing measurement time.

Main Methods:

• Implementation of Hadamard encoding within an excitation sculpting framework.
• Application of HEX sculpting to selective 1D and NOESY1D NMR experiments.

Main Results:

• HEX sculpting significantly reduces the total measuring time required to achieve a target signal-to-noise ratio (S/N).
• The method is effective for band- and/or frequency-selective experiments performed at multiple sites.

Conclusions:

• Hadamard excitation sculpting offers an efficient strategy for accelerating NMR experiments.
• This approach is particularly beneficial for complex selective NMR experiments, improving overall experimental throughput.
