Peculiarities of NMR 1H and 13C spectra of alkyl groups in functionalized linear alkanes of the general formula CH3(CH2)MY

A new universal method of estimating the chemical shifts values of the methylene groups. Change the values of 1H and 13C each methylene group in the result of the conversion by replacing the long fragments –(CH2)K– and –(CH2)I– of the Vice alculated.
