Such electronic structures are rationalized by utilizing the degeneracy of non-bonding pi molecular orbitals (NBMO) ... stable spin multiplicity depends on the bond angle 0. In the gaseous phase the triplet state 3 E (or 3B1) is stable for nearly linear methylene ... Web4. SIGNAL MULTIPLICITY AND SPIN-SPIN SPLITTING. Each signal in a proton NMR spectrum may or may not be split into one or more peaks. This is called signal multiplicity and gives rise to names such as singlet, doublet, triplet, quartet, pentet, and multiplet. The most common concept associated with signal multiplicity is the n+1 rule.
