Discuss the instrumentations of the NMR spectrometer.
Accepted Answer
The core of an NMR spectrometer is a powerful magnet that creates a strong magnetic field. This field aligns the nuclear spins of the sample.
Here's a breakdown of the key components:
Magnet: The heart of the instrument. Creates the strong magnetic field needed to align nuclear spins.
Radiofrequency Transmitter: Sends radio waves into the sample, exciting the aligned nuclei.
Sample Probe: Holds the sample and allows for efficient interaction with the radio waves.
Radiofrequency Receiver: Detects the radio waves emitted by the excited nuclei as they relax back to their original state.
Computer: Processes the detected signal and generates the NMR spectrum.
NMR spectrometers are typically classified based on the strength of their magnets, measured in Tesla (T). Higher field magnets provide better resolution and sensitivity, but they are also more expensive.
