Our molecular rotational resonance (MRR) spectroscopy instruments identify molecular structures directly from liquids, gases, or headspace — no derivatization, chromatography, or sample prep required. By measuring a molecule's unique rotational fingerprint, MRR delivers definitive structure ID in minutes, eliminating the time, uncertainty, and cost of traditional workflows. As AI-driven molecular design accelerates de novo molecules, MRR is the ideal structural validation tool; it identifies these novel compounds without reference standards, using only quantum-predicted spectra for unambiguous confirmation.
