  • 1

    A phosphoric acid dimer structure was identified via cryogenic spectroscopy.

  • 2

    Structure A1 contains three hydrogen bonds across five oxygen atoms.

  • 3

    The study utilized helium nanodroplet and D₂-tagging infrared spectroscopies.

  • 4

    Experimental results emphasized the importance of structural validation.

  • 5

    The findings may aid in better quantum chemical models for phosphoric acid clusters.
