In mass spectrometry blackbody infrared radiative dissociation (BIRD) is a method for fragmenting 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.[1][2] This is very similar to infrared multiphoton dissociation with the exception of the source of radiation.[3] This technique is most often studied in Fourier transform ion cyclotron resonance mass spectrometry.
