Angular streaking for strong field ionization of molecules-attosecond physics without attosecond pulses

The angular streaking of a close-to-circular polarized ultrahsort laser pulse provides a powerful tool and opens new possibilities for attosecond physics without the using of attosecond pulses. For strong field ionization of molecules we discuss in this review how this technique allows to uncover the intrinsic phase-dependent directional molecular bond breaking in a symmetric multicycle laser pulse (Sect. 3.2), how it allows probing the tunnelling site of the freed electron in the electron localizationassisted enhanced ionization of molecules near the critical internuclear distance (Sect. 3.3), how it reveals the orientation-dependent tunnelling ionization rate of polar molecules without pre-alignment of the molecules (Sect. 3.4), and how to use it to sequence the release order of the freed electrons in multielectron ionization of a multicenter molecular dimer (Sect. 3.5).
