We exploit the relationship between higher-order harmonic generation (HHG) and photoionization to extract information of the molecular and atomic quantum states. We generate harmonics from very well-aligned molecules, which allow us to make a direct comparison with state of the art theoretical models. Unlike traditional methods, we are able to observe a very rich molecular structure in the molecular frame. Such rich structures include angle and energy dependent resonances and minima and multi-electron effects. In addition, we observe and directly measure contributions to the harmonic generation from different molecular orbitals for the first time. Finally, I'll discuss new optics developments that will potentially have a great impact in the field of strong field-matter interaction and attosecond science.
