Transient absorption is a very powerful observable in attosecond experimentson atoms, molecules and solids and is frequently used in experiments employingphase-locked few-cycle infrared and XUV laser pulses derived from high harmonicgeneration. We show numerically and analytically that in non-centrosymmetricsystems, such as many polyatomic molecules, which-way interference enabled bythe lack of parity conservation leads to new spectral absorption features,which directly reveal the laser electric field. The extension of AttosecondTransient Absorption Spectroscopy (ATAS) to such targets hence becomessensitive to global and local inversion symmetry. We anticipate that ATAS willfind new applications in non-centrosymmetric systems, in which thecarrier-to-envelope phase of the infrared pulse becomes a relevant parameterand in which the orientation of the sample and the electronic symmetry of themolecule can be addressed.
