We investigate how short and long electron trajectory contributions to highharmonic emission and their interferences give access to intra-moleculardynamics. In the case of unaligned molecules, we show experimental evidencesthat the long trajectory signature is more dependent upon the molecule than theshort one, providing a high sensitivity to cation nuclear dynamics within 100'sof as to few fs. Using theoretical approaches based on Strong FieldApproximation and Time Dependent Schrodinger Equation, we examine how quantumpath interferences encode electronic motion whilst molecules are aligned. Weshow that the interferences are dependent on channels superposition and uponwhich ionisation channel is involved. In particular, quantum path interferencesencodes electronic migration signature while coupling between channels isallowed by the laser field. Hence, molecular quantum path interferences is apromising method for Attosecond Spectroscopy, allowing the resolution ofultra-fast charge migration in molecules after ionisation in a self-referencedmanner.
