摘要：

The elusive triplet state of indigo (see picture) has been fully characterized by energy-transfer pulse radiolysis and photoacoustic calorimetry. The triplet energy is (1.04 ± 0.10) eV and the singlet-to-triplet intersystem crossing yield in solution is φISC = 0.0066. Inefficient intersystem crossing, low triplet energy, and fast internal conversion of the singlet state likely contribute to the high stability of indigo.
