Sentences with phrase «ion cyclotron»
We use a combination of experimental studies of collisional activation and dissociation of complex molecules in a Fourier transform ion cyclotron resonance mass spectrometer with RRKM modeling to determine the internal energy distribution of excited ions and the energetics and dynamics of dissociation for the ion of interest.

Ion cyclotron frequency is the number of times per second that the electrons and ions circle around the field line.
A type of wave that can exist in a plasma (such as the region of space above Earth's aurora), which vibrates at an ion cyclotron frequency that corresponds to the ion type present (oxygen, helium, hydrogen, etc.).
This flickering typically oscillates at a 1/10 second period, which is equivalent to the ion cyclotron frequency (* 1) of oxygen ions.
«The fact that this high - speed flickering was observed at the same time as flickering with a typical 1/10 second period may mean that the flickering aurora was caused by «electromagnetic ion cyclotron waves» (* 2), which are affected by both oxygen and hydrogen ions.»
We used Fourier - transform ion cyclotron resonance mass spectrometry and nuclear magnetic resonance spectroscopy to show that a sulfilimine bond -LRB-- S = N --RRB- crosslinks hydroxylysine - 211 and methionine - 93 of adjoining protomers, a bond not previously found in biomolecules.
