Nuclei with an _____________ number of protons and neutrons possess a property called spin. Nuclear spin can be thought as eithe
andriy [413]

Answer:

Explanation:

\text{We are to fill in the blanks with the correct words that best suit the blanks}

\text{Nuclei with an} \ \mathbf{odd}  \  \text{number of protons and neutrons possess a property }

\text{called spin. Nuclear spin can be thought as either up or down with the spin }

\mathbf{magnetic \  field.}

\text{When a molecule is placed in an NMR, a large}  \ \mathbf{magnetic}  \ \text{field is applied making the }\text{spin states become of unequal energy, with the spin that generates a magnetic field  }\text{in the same direction of the applied magnetic field being}\ \mathbf{ lower} \ \text{ in energy. The NMR }\text{then uses} \ \mathbf{ radio \ frequency}\ \text{ to 'flip the spin' of each nuclei, wherein each nuclei will }\text{require a specific energy level of radiation that corresponds to its difference in  }\text{energy of spin states, this is often called the nuclei's}\  \ \mathbf{resonance } \  \text{frequency, } \text{which is measured by the NMR and translated to teh final spectra.}
