In a series of 2-X-fluorobenzenes, the relative signs between 'J(CF) and the corresponding 4J(HF) couplings were determined. In most cases like signs were found. However, for the coupling pathway involving the X group, unlike signs were found for X = CN, NCS and NO,. For other electronegative substi
