## Abstract The ^13^C chemical shifts and oneβbond carbonβhydrogen coupling constants have been obtained for some hydroxycoumarins and their corresponding acetoxy and methoxy derivatives. The changes in the oneβbond carbonβhydrogen coupling constants resulting from the conversion of a hydroxy group
