Researchers have developed UltraIR, a foundation model for infrared spectroscopy designed to improve chemical sensing and analysis. This model, with over 100 million parameters, utilizes simulation-to-real transfer learning, pretraining on approximately 60 million simulated spectra. UltraIR demonstrates superior performance across various tasks, including functional-group prediction, molecular structure elucidation, and sample classification, outperforming traditional machine-learning methods. It shows strong capabilities even with limited labeled experimental data and in zero-shot inference scenarios across different spectrometers and laboratories. AI
