A Doorway mechanism for Electron Attachment Induced DNA Strand Break

Jishnu Narayanan S J, Divya Tripathi, Achintya Kumar Dutta

We report a new doorway mechanism for the dissociative electron attachment to genetic materials. The dipole-bound state of the nucleotide anion acts as the doorway for electron cap…

Electron attachment to Cytosine: The Role of Water

Pooja Verma, Debashree Ghosh, Achintya Kumar Dutta

We present an EOM-CCSD based QM/MM study on the electron attachment process to cytosine, solvated in water. The microhydration studies cannot capture the effect of bulk water envir…

A Core-Valence Separated Similarity Transformed EOM-CCSD Method for Core-excitation Spectra

Santosh Ranga, Achintya Kumar Dutta

We present the theory and implementation of a core-valence separated similarity transformed EOM-CCSD (STEOM-CCSD) method for K-edge core excitation spectra. The method can select a…
