  But despite frequent theorizing to the contrary, the lower-frequency beams don't ionize; they pack just enough punch to penetrate and reflect but not to separate electrons from atoms entirely.
  Evidently, any disruption of the HB-net between Glu - 222 and Tyr - 66 should eliminate the Cro reprotonation in the GS, which would then remain permanently ionized.

ionization

noun ˌʌɪənʌɪˈzeɪʃ(ə)n

Example sentencesExamples
