Are disulfide bonds resilient to double ionization? Insights from coincidence spectroscopy and ab initio calculations
(2020)
Disulfide bonds (–S–S–) are commonly present in biomolecules and have also been detected in astrophysical environments. In this work, the stability of the disulfide bond towards double ionization is investigated using ...
Breaking the disulfide chemical bond using high energy photons: the dimethyl disulfide and methyl propyl disulfide molecules
(2017-07-15)
In order to study the stability of the disulfide chemical bond in molecules subjected to a flux of high energy photons, the ionic fragmentation of two molecules containing a disulfide chemical bond, dimethyl disulfide ...
Interstellar H3+ and HCS+ Ions Produced in the Dissociative Photoionization Process of CH3C(O)SCH3 in the Proximity of the Sulfur 2p, Carbon 1s, and Oxygen 1s Edges
(American Chemical Society, 2012-02)
In this work we present a study of the dissociative photoionization of S-methyl thioacetate [CH3C(O)SCH3] by using multicoincidence time-of-flight mass spectrometry and synchrotron radiation in the S 2p, C 1s, and O 1s ...
