3.7.2 Hidden Doublets
Relevant doublets of weak intensity are often largely hidden under other, more
intense doublets or inner lines of sextet components and their presence will gen-
erally not be recognized although they have hyperfine parameters that deviate from
the predominant doublets. In order to overcome this shortcoming to some extent, it
is always advisable to throw a closer look at the central part of the spectrum.
