摘要：

A method for the calculation of NMR shieldings is presented, which allows for the first time the study of molecular systems with one thousand and more atoms at the ab initio level (see picture), by reducing the computational scaling from cubic to linear. This opens new possibilities for the often difficult assignment of experimental NMR spectra.
