Molecular ionization by femtosecond light pulses is fascinating phenomena in terms of both the underlying physics and practical implications to selective control of isomerization and fragmentation pathway(s) through the shape of the optical waveform. Triggered by optical field ionization, the outcome of the complex electronic and subsequent nuclear dynamics leading to fragmentation is to a large extent predetermined on a subcycle time scale because of a sharp temporal localization of electron release to an attosecond interval at the peak of an intense optical half-cycle. Consequently, as has been shown in the case of diatomic molecules[1,2] — dissociative ionization strongly depends on the carrier-envelope phase (CEP) of a few-cycle laser pulse.
