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.

The diasteromers of 4-t-butylcyclohexanol that you make can be distinguished by the splitting patterns of the proton attached to the carbon bearing th OH group. This is due to the fact that the H that is axial is a triplet of triplets because it is coupled to to sets of non-eqivalent protons, while the equatorial H is coupled to 4 equivalent hydrogens and is a pentet. True? False? Please answer very soon will give rating surely Complete explaination needed
