Researchers have developed MAST, a novel diffusion-based framework designed to improve the elucidation of molecular structures from spectroscopic data. MAST incorporates interpretable motif priors as intermediate evidence during the denoising process, which helps to reduce ambiguity and enhance spectra-conditioned optimization. The framework also employs a reward-guided tree search for diffusion sampling, prioritizing efficient denoising trajectories to generate a concise set of spectra-consistent candidates. In tests on the QM9S benchmark, MAST demonstrated a high exact recovery rate of 94.89% and improved 3D fidelity while maintaining chemical validity and stability. AI
