MASS SPECTRA OF MOLECULES

EXPERIMENT 3: INTERPRETING MASS SPECTRA OF MOLECULES AIM: To identify all the peaks in the given spectra. Assuming that each peak is due to a singly charged species. Also assume that one isotope for each element except chlorine. METHOD: _ Identify the peak present in the mass spectrum of argon gas. _ Identify the peaks present in the mass spectrum of nitrogen gas. _ Identify the peaks present in the mass spectrum of nitrogen dioxide. _ Identify the peaks present …

…for the molecule OF2: CONCLUSION: The mass spectrometer has many applications, one of them is to determine the natural abundances of the isotopes of a particular element and hence allow calculations of its atomic mass. It also measure relatives atomic masses, finds the relative abundance of isotopes in a sample of an element and examines the fragments that a molecule might break into so that the identiy of that molecule can be found. And structure.
