Labelling problems associated with the choice of bounds for the angle θ in the trigonometric forms of the co‐factor expressions for levels in AB‐based NMR spectra have been investigated. It has been shown that any pair of octants within the 0 → 2π range can be specified as bounds, provided that appropriate linear combinations of wave functions are chosen. The range 0 ⩽ θ ⩽ π/2 is preferred for simplicity in calculation.
