PG entrance exam CUET PG 2025 Mock Test Chemical Sciences Structure Determination of Organic Compounds 1h NMR and 13c NMR Spectroscopy
The correct statement in the context of NMR spectroscopy is
1
static magnetic field is used to induce transition between the spin states
2
magnetization vector is perpendicular to the applied static magnetic field
3
the static magnetic field is used to create population difference between the spin states
4
static magnetic field induces spin-spin coupling
