Question

Which of the following is false about NMR spectroscopy?

(a) NMR is an abbreviated form of Nuclear Magnetic Resonance

(b) The intramolecular magnetic field around an atom in a molecule changes the resonance frequency giving structural information about the atom

(c) The intermolecular magnetic field around an atom in a molecule changes the resonance frequency giving structural information about the atom

(d) It is a technique that exploits magnetic properties of atomic nuclei

This question was addressed to me during an interview.

The above asked question is from Protein Secondary Structure in chapter Three Dimensional Structure Of Proteins and Protein Function of Biochemistry

Answer 1

Right option is (c) The intermolecular magnetic field around an atom in a molecule changes the resonance frequency giving structural information about the atom

For explanation I would say: The intramolecular magnetic field around an atom in a molecule changes the resonance frequency giving structural information about the atom.
