text: Although paramagnetic, this species is unlikely to be detected by epr because of (1) zerofold splitting of the S = 2 ground state, which shifts allowed transitions to inaccessible magnetic fields and (2) unusually short spin-lattice relaxation times.

text: Li et al. [40] proposed a different classification for protein coding nucleotide sequences. They classified sites into fourfold, twofold, and zerofold degenerate (nondegenerate in their original terminology) classes.[…]Many of the first-codon positions are also classified as zerofold degenerate sites, and exceptions are those for four Arg codons and four Leu codons, which are classified as twofold degenerate. The third positions of Met and Trp codons are also zerofold degenerate sites.
