## 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
## Abstract A study has been made of the ^13^C chemical shifts of a number of acyclic alkanes, alkenes, nitriles and ketones which contain quaternary carbon atoms. Similar data have also been obtained for the series of compounds involved in the synthesis of triisopropylacetic acid. Substituent effe
13C NMR data are presented for 31 variously substituted derivatives of 9acridanone and 15 derivatives of 9-thioacridanone. Unexpected shifts are explained in terms of hydrogen bonding or tautomeric equilibria.
