Below is the spectrum for 2-hexanol which has a molecular ion peak of 102. Note that 2-hexanol's molecular ion is very unstable and rapidly undergoes degradation.  This is why its molecular ion peak at 102 is almost nonexistent.  Give the formula and try to describe the structure that corresponds to the base peak within the spectrum.

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.
