Concept explainers

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

How many signals will be found in the 13c NMR of 2 propanol at room temperature

Expert Solution

Carbon-13 NMR

¹³C - NMR is analogous to proton NMR. This process does identification of carbon molecules in organic compounds same as proton NMR identifies hydrogen.

Tetramethylsilane (TMS) is used as reference in ¹³C NMR.

Each carbon atom show different chemical shift as it has different chemical environment. But when structure is symmetrical NMR signals reduce. crobon atoms having same chemical environment show one signal.
