TI  - The inner-shell ionization and fragmentation of selenophene at 120 eV

AB  - Three-dimensional velocity-map imaging and covariance analysis were used to identify over 50 fragmentation channels produced following the inner-shell ionization of selenophene at 120 eV. The majority resulted in two or three 'heavy' products containing selenium or carbon, many of which had identical mass-to-charge ratios but different chemical compositions due to the degree of hydrogenation and the selenium isotope involved. Covariance analysis was used to isolate these reaction channels and to provide estimates of their relative yields. In combination with prior similar studies on thiophene and furan, the current results indicate that the nature of the heteroatom significantly influences the charge redistribution and bond cleavage dynamics induced by the Auger-Meitner process, and demonstrate the sensitivity of inner-shell ionization dynamics to the molecular and electronic structures of heterocyclic systems.
