Spectra Edited by Relative Signs of Homonuclear Couplings of Low Abundant Nuclei
Original language description
The proposed Homonuclear Coupling Sign Edited (HCSE) experiment can detect signed homonuclear couplings between low abundant nuclei like 13C, 29Si and 15N in linear spin systems, i.e. in systems where two nuclei are coupled by the measured coupling and one of them is coupled by a second coupling to a nucleus of different kind. The third nucleus is usually high abundant hydrogen. Two spectra are measured during the HCSE experiment. Their weighed sum and difference yield two other spectra, one containingpeaks coupled only by positive measured couplings and the other having peaks coupled by negative measured couplings. The usual E.COSY-type experiment requires all three couplings in the three spin system (triangular spin system) and not only two couplings as the HCSE experiment. A set of six simple siloxanes with |2J(Si-O-Si)| couplings ranging from 0.5 Hz to 9.0 Hz was measured for the first time and all the couplings were found to be positive.
