Notes:
The use of one-dimensional total correlation spectroscopy (1D TOCSY) combined with the z-filtration technique to generate pure phase subspectra of individual isomers from the spectrum of the corresponding mixture without any chemical separation of the mixture is described. A straightforward spectral assignment is achieved for the isomers obtained on lithium aluminium hydride reduction of 2,7-dioxatetracyclo[3.3.04,9.08,11] undeca-3,6-dione (dilactone) by studying the subspectrum of each isomer as a function of the propagation time of magnetization through the network of coupled protons.
