abstract = {We present results from an experimental ion imaging study
into the fragmentation dynamics of 1-iodopropane and
2-iodopropane following interaction with extreme ultraviolet
intense femtosecond laser pulses with a photon energy of 95
eV. Using covariance imaging analysis, a range of observed
fragmentation pathways of the resulting polycations can be
isolated and interrogated in detail at relatively high ion
count rates (∼12 ions shot$^{−1}$). By incorporating the
recently developed native frames analysis approach into the
three-dimensional covariance imaging procedure,
contributions from three-body concerted and sequential
fragmentation mechanisms can be isolated. The angular
distribution of the fragment ions is much more complex than
in previously reported studies for triatomic polycations,
and differs substantially between the two isomeric species.
With support of simple simulations of the dissociation
channels of interest, detailed physical insights into the
fragmentation dynamics are obtained, including how the
initial dissociation step in a sequential mechanism
influences rovibrational dynamics in the metastable
intermediate ion and how signatures of this nuclear motion
manifest in the measured signals.},
