Statistical analysis of 13C and 15N NMR chemical shifts from GIAO/B3LYP/6-311++G** calculated absolute shieldings

The ¹³C and ¹⁵N absolute shieldings of 28 compounds have been calculated at the GIAO/B3LYP/6-311 + + G** level to complete a collection of data already published. This has allowed us to devise new equations relating δ and σ for these nuclei based on 461 points (¹³C) and 70(72) points (¹⁵N).
