Double proton-proton resonance of substituted polychlorbicyclo[2.2.1]heptenes

Conclusion The given analysis of the four spin AABB system shows that the use of the INDOR technique substantially simplifies the problem of analyzing spectra as compared with the methods of identification which have been previously used [14, 16], which, although they lead to the desired result, make excessive demands on machine time and require running a number of trial assignments. It should be noted that INDOR does possess the disavantage of a loss of sensitivity as compared with conventional spectra which imposes some restriction on its use in the analysis of spectra of difficultly soluble compounds.Institute of Chemical Physics, Academy of Sciences of the USSR.
