Relativistic effect of iodine in 13C NMR chemical shifts of iodomethanes from quantum chemical calculations within the framework of the full four-component relativistic Dirac—Coulomb scheme
Autor: Leonid B. Krivdin, D. O. Samultsev, Yu. Yu. Rusakov
Publikováno v: Russian Chemical Bulletin. 64:2756-2762
13C NMR shielding constants (chemical shifts) of iodomethanes were calculated within the framework of the full four-component relativistic Dirac—Coulomb scheme. As the number of iodine atoms in the molecule increases, the relativistic counterpart o
