Electron attachment to the N-substituted amino acids N-methylglycine and N-methylalanine: Effective cleavage of the N–Cα bond at sub-excitation energies

Electron scattering from molecules and molecular aggregates of biological relevance

“…The R-matrix method has been used to determine parameters for all shape and some core-excited resonances in all DNA bases at equilibrium geometry (Dora et al 2009, 2012a, 2012b. The positions of the * p shape resonances calculated at CC level agree better with experiment (Aflatooni et al 1998) than any previous work for cytosine and thymine whereas for guanine and adenine, the agreement is similar to that of the Schwinger SEP results (Winstead and McKoy 2008).…”

Low energy electron induced reactions in fluorinated acetamide – probing negative ions and neutral stable counterparts*

“…Prototype electron scavengers are the chlorofluorocarbons (CFCs) with the peculiar properties that they are often photochemically remarkably stable, while they are very sensitive towards electrons with virtually no extra energy [8][9][10] thereby decomposing via DEA. Over the last 15 years or so extensive studies on biologically relevant molecules including DNA bases [11,12], sugars [13,14], and amino acids [15,16] revealed that these compounds are generally very sensitive towards low energy electrons (LEEs) [17][18][19][20], i.e., they possess low energy resonances leading to decomposition. And hence low energy electrons are considered to play a particular role in radiation damage.…”
