Strong field non sequential double ionization (NSDI) has attracted a great deal of attention since it directly probes electron correlation (correlated electron dynamics), which lies at the core of attosecond science. Numerous experimental and theoretical studies have been focused on NSDI on atoms, while in the case of molecules is relatively unexplored, particularly for polyatomic systems. We present coincidence velocity map imaging measurements of molecular double ionization in cyclohexadiene using few cycle (∼ 10 fs) laser pulses. These  measurements, along with electronic structure calculations, allow us to distinguish between dissociative and non-dissociative double ionization, and we find a difference in the correlation of electrons that come from the different channels.
