Deep4Chem: AI Optical Spectrometer


Accurate and reliable prediction of various optical properties of organic compounds is very important for developing new organic compounds with desired properties. Here, we have developed an artificial intelligence (AI) optical spectrometer, Deep4Chem, using deep learning methods and experimental database of optical properties of organic compounds in various solvents, host films, and solid states.
