A series of reaction microscope experiments on strong-field ionization and laser-driven electron rescattering of the asymmetric top molecule 1,3-butadiene is presented. Importantly, by virtue of the ion-electron coincidence detection, these experiments separate the ground-state (D0) and first excited state (D1) ionization channel. By analyzing coherent rotational wavepacket evolution we extract the polar and azimuthal angle-resolved molecular frame ionization and rescattering probability. By extracting the differential scattering cross section (DCS) for near- to mid-infrared wavelengths we explore the role of different continuum wavepackets for molecular structure determination. By measuring the ellipticity dependence of the return-energy dependent rescattering probability we explore the role of short versus long trajectories. A multi-faceted picture of molecular effects in strong-field ionization and laser-induced electron diffraction ensues.
