The electronic transitions of the peptide bond occur in the far UV. The intense peak at 190 nm, and the weaker one at 210–220 nm is due to the p!p* and n!p* transitions.

The slow return of the K + channels to the closed state also explains the after-hyperpolarization, followed by a return to the resting membrane potential
