Question

What are the advantages of an FT-NMR measurement over a CW measurement? What are the disadvantages?

Short answer

FT-NMR measurement saves time and has high sensitivity as compared to CW measurement. FT-NMR measurements are expensive and need high maintenance.

Step-by-step solution

Step 1. Given information

The advantages and disadvantages of FT-NMR measurement over a CW measurement should be determined.

Step 2. Advantages of an FT-NMR measurement over a CW measurement

1. FT-NMR takes less time to examine nuclei under the magnetic field while CW needs a lot of time.

2. FT-NMR has a high signal averaging towards the fewer abundance nuclei like ${}^{13}\mathrm{C}$, ${}^{31}\mathrm{P}$and ${}^{19}\mathrm{F}$while CW is used for ${}^1\mathrm{H}$NMR.

Step 3.  Disadvantages of an FT-NMR measurement over a CW measurement

1. FT-NMR spectrometer requires high maintenance.

2. FT-NMR requires high operational costs.
