The 13C n.m.r. spectra of a series of 37 bicyclic ketones have been recorded to examine the variations in 13C shieldings with structure and with methyl substitution. Several examples of six skeletal types were included: bicyclo[4.4.0]decanones, bicyclo[4.1.0]heptanones, bicyclo-[3.1.0]hexanones, bicyclo[3.2.2]nonanones, bicyclo[3.2.1]- and -[3.3.0]octanones as well as bicyclo[2.1.1]hexan-2-one, nopinone
