## Abstract An approach to spinning sideband (SSB) separation of protonated and nonβprotonated carbons in slow spinning conditions via dipolar dephasing is proposed. This method offers two features: SSB spectral simplification, which greatly reduces the overlaps encountered in a usual SSB spectrum,

## Abstract Selected model carboxylic acids and esters dissolved in deuteriochloroform have been studied by carbonβ13 nuclear magnetic resonance under standardized conditions. Assignments of the chemical shifts have been made for all samples, and the spinβlattice relaxation times and nuclear Overha
2-Methoxyethanol chemical ionization of amines, carboxylic acids and amino acids has been found to produce numerous adduct ions. The most intense adduct ions for amines are [M H] and [M 77] , for carboxylic acids [M 27] , [M 59] and [M 77] , and for amino acids [M H] , [M 13] , [M 27] and [M 77] . E
