Abstract	We present an overview of our lab activities on strong field High Harmonic Generation in Molecules. The symmetry of the molecular electronic orbitals influences the amplitude and phase of the emitted high harmonics, as we show in calculations for N₂ and CO₂[1]. We present experimental data using HHG on an aligned ensemble on N₂ molecules. The phases are measured via referencing to argon high harmonics. An amplitude minimum in the harmonics is related to a 180 degree phase jump in agreement with the theory. The understanding of this process opens possibilities for attosecond pulse shaping.
