【 摘 要 】

We show experimentally and theoretically, using acetylene as an example, that the strong preponderance of ionization from specific molecular orbitals to the alignment of the molecular axis with respect to the laser polarization direction allows implementing a method for controlling fragmentation reactions of polyatomic molecules.
