Triplet state properties of pyridinium

Pyridinium phosphorescence originates at 334 nm and has a lifetime of 3.5 s; the quantum yield is roughly 0.04. The ODMR spectrum gives a zero-field splitting of |D| = 0.134 cm −1, |E| = 0.030 cm −1 . Implications for the lowest triplet state of pyridine are discussed.
