Definitions:

M/Z = 43

Represents the mass-to-charge ratio of 43 in mass spectrometry, indicative of a specific fragment's mass.

Molecular Ion Peak

The peak in a mass spectrum that represents the molecule of the sample as a positively charged ion.

Fragment Peaks

Fragment peaks in mass spectrometry refer to the peaks that represent the masses of fragments from the molecule being ionized and broken apart, aiding in the determination of molecular structure.

M/Z Fragment

Refers to the mass-to-charge ratio of ions observed in mass spectrometry, crucial for identifying and characterizing molecules based on their fragmentation patterns.
