Help on NMR Spectroscopy For a time-domain signal in which the NMR signal has decayed long before the end of the acquisition time, explain why the SNR of the corresponding spectrum can be improved either by shortening the acquisition time, or by applying a suitable weighting function.
Homework Answers
Answer:
- Shortening the procurement time disposes of the time-space information that contains for the most part commotion and minimal sign.
- Applying a line widening weighting capacity doesn't dispose of this area of the time-space, yet diminishes its abundancy with respect to the prior piece of the FID.
- Subsequently, the two strategies lessen the force of the commotion in the range.
