In mass spectrometry

Mass spectrometry

Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles.It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical structures of molecules, such as peptides and...

 blackbody infrared radiative dissociation (BIRD) is a method for fragmenting

Fragmentation (chemistry)

Fragmentation is a type of chemical dissociation. Fragmentation of a molecule can take place by a process of heterolysis or homolysis.It is a phenomenon observed in mass spectrometry where it is used as a tool to find the structural formula of a molecule, process called structural elucidation.It...

 gas phase ions for tandem mass spectrometric analysis (structural elucidation). BIRD uses the light from black body radiation to thermally (vibrationally) excite the ions until a bond breaks. This is very similar to infrared multiphoton dissociation

Infrared multiphoton dissociation

Infrared multiphoton dissociation is a technique used in mass spectrometry to fragment molecules in the gas phase usually for structural analysis of the original molecule. -How it works:...

 with the exception of the source of radiation. This technique is most often studied in Fourier transform ion cyclotron resonance

Fourier transform ion cyclotron resonance

Fourier transform ion cyclotron resonance mass spectrometry, also known as Fourier transform mass spectrometry, is a type of mass analyzer for determining the mass-to-charge ratio of ions based on the cyclotron frequency of the ions in a fixed magnetic field...
