The correct statement in the context of NMR spectroscopy is:a)Static m...
Explanation:
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that is used to determine the physical and chemical properties of molecules. It relies on the interaction of nuclear spin with an external magnetic field, which generates a measurable signal that can be used to obtain information about the molecular structure and dynamics.
The correct statement in the context of NMR spectroscopy is:
Magnetization vector is perpendicular to the applied static magnetic field.
This statement is true because the magnetization vector, which is the net magnetic moment of the sample being studied, is oriented perpendicular to the applied static magnetic field. This is because the magnetic field induces precession of the nuclear spins around the direction of the field, causing them to align with the field in either an up or down orientation. The net magnetization vector is the sum of all the individual spin vectors and is perpendicular to the applied magnetic field.
Other statements in the context of NMR spectroscopy are:
Static magnetic field is used to induce transition between the spin states.
This statement is partially true. The static magnetic field is used to split the energy levels of the nuclear spins, creating a population difference between the spin states. This difference in population is what allows for transitions to occur when radiofrequency pulses are applied.
The static magnetic field is used to create population difference between the spin states.
This statement is true. The static magnetic field creates a difference in energy between the spin states, which results in a difference in population of the spin states.
Static magnetic field induces spin-spin coupling.
This statement is also true. The static magnetic field can induce spin-spin coupling, which is the interaction between the magnetic moments of two different nuclei. This coupling can result in splitting of the NMR signals, providing additional information about the molecular structure and dynamics.
