Description
The magnetic equivalence among nucleus may be forecasted through the use of symmetry tests or scalar coupling equivalence. A few molecules can present accidental equivalence, when their spectrum shows a un predictable simplified form. This paper describes how the performance of several components responsible for the nuclear shielding may propitiate this coincidence, and how neutralize it
