WebThe ionizable groups are the amino and the carboxyl. The amino group has a pKa of 9.0 and the carboxylate has a pKa of 2.0. The amino group has a charge of +1 when protonated, 0 when deprotonated. The carboxylate has a charge of 0 when protonated, -1 when deprotonated. Step 2. The electron is ionized through multiphoton coupling with the continuum. As the intensity of the pulse is increased the excited state and the continuum are shifted in energy due to the Stark shift. At the peak of the pulse (b) the excited states go into multiphoton resonance with the ground state.
