AN EXCEPTION TO THE CIDNP SIGN RULES
It is demonstrated experimentally that the CIDNP sign rules can give erroneous results. Net effects observed in the 1H NMR spectrum of 1-phenyl[2-13C]propan-2-one after photolysis are correctly predicted at 360 MHz but not at 100 MHz by the rules. The converse is true for the 1H-13C multiplet effect...
