Publication Summary
Originally published in Analytical Chemistry, this study demonstrates the integration of laser-induced acoustic desorption (LIAD) with molecular rotational resonance (MRR) spectroscopy to enable the analysis of low-volatility and thermally sensitive compounds that are difficult to introduce into the gas phase using conventional sample preparation methods. By coupling LIAD with MRR, the researchers expanded the range of molecules accessible to structure-specific rotational spectroscopy while preserving molecular integrity during desorption.
The work highlights LIAD as a gentle sample introduction technique that broadens the applicability of MRR spectroscopy beyond highly volatile analytes. The authors demonstrate successful analysis of challenging molecules and show that LIAD-MRR can provide detailed molecular identification and structural characterization without requiring extensive sample modification or derivatization. The results establish LIAD as a promising tool for extending MRR spectroscopy to new classes of compounds and analytical applications.
