What is the difference between the parent peak and base peak in mass spectroscopy?
Added by Cynthia C.
Step 1
Parent Peak: Also known as the molecular ion peak, this is the peak that represents the original molecule's mass-to-charge ratio (m/z). It is usually the peak with the highest m/z value in the spectrum. This peak is produced when the molecule is ionized without Show more…

Explain why the base peak and the signal for the molecular ion usually are nonidentical. Draw a labelled, generic mass spectrum to illustrate your answer.
Adi S.
In mass spectrometry, the tallest peak is assigned an intensity of 100% and is referred to as which of the following? A : daughter ion B : fragment C : parent ion D : base peak E : molecular ion
The peaks shown by the mass spectrum are given in terms of relative abundance, where the strongest peak (also known as the base peak) is assigned a value of 100%. On the other hand, the parent peak (also known as the molecular ion peak) is the peak shown by the molecular ion M+ after losing only one electron (without undergoing any fragmentation). Will this parent peak always be the base peak? True or False.
