Investigation on structures in the high-harmonic spectrum has provided profuse information of molecular structure and dynamics intense laser fields, based which techniques ultrafast imaging have been developed. Combining ab initio calculations experimental measurements CO_{2} molecule, we find a novel dip low-energy region harmonic is identified as fingerprints participation deeper-lying orbitals process decodes underlying attosecond multichannel coupling dynamics. Our work sheds new light molecules fields.
