Abstract
We present a detailed study on the fragmentation of proline (Pro, C5H9NO2) upon attachment of low energy electrons (<12Â eV). Previous investigations on dissociative electron attachment to Pro are partly confirmed, extended and also in some points vitiated. A total of 11 fragment anions, with [Pro-H]â being the most abundant one, has been observed and the present results indicate that the formation of [glycil-yl]â from Pro cannot be induced by slow electrons. This work supplements existing work on amino acids and therefore improves the understanding of the interaction between electrons at sub-ionization energies and molecules of biological interest.
