Abstract
A new pulse sequence which allows selective excitations of carbons according to their multiplicity is described. The method is tested with an ionophorous antibioticο£Ώthe sodium salt of lysocellin, C~34~H~60~O~10~.

Assignment of the 1H and 13C signals arising from the carbohydrate portion of sucrose octabenzoate has been achieved using homonuclear shift correlation experiments (COSY) and one-bond 1H-13C heteronuclear shift correlation measurements, respectively. The 13C resonances of the carbonyl carbon atoms
## Abstract The high temperature ^13^C NMR spectra of the methyl esters of deuteroporphyrinβIX and protoporphyrinβIX, and octaethylporphyrin show sharp discrete signals for the inner macrocycle carbon resonances. The temperature dependence of these shifts is discussed.
