(a)
Interpretation:
The high-resolution proton NMR spectrum of ethyl nitrite is to be stated.
Concept introduction:
The nuclear magnetic resonance (NMR) instrument analyzes the material’s molecular structure by placing the material in the strong magnetic field and measuring the spins.
The NMR spectroscopy measures the following property of the material molecules.
- Chemical shift:
Appearance of the atomic group composition in the molecule.
- The spin-spin coupling constant:
It provides information about the appearance of the adjacent atoms.
- Relaxation time:
It provides information about molecular dynamics.
- Signal intensity:
It provides the quantitative information about the atomic ratios within a molecule which determines the molecular structure, and proportions of different compounds in a mixture.
