Fourier series of atomic radial distribution functions: A molecular fingerprint for machine learning models of quantum chemical properties
We introduce a fingerprint representation of molecules based on a Fourier series of atomic
radial distribution functions. This fingerprint is unique (except for chirality), continuous, and …
