✦ Synopsis
The zero-flcld cphtting of the triplet \tnte of mqncsmmporphin solvatcd by ethzmol is rcprcsented by D = 0.035 cm-t and KI = 0.010 cm-'. The decay rates of the upper two spin componenti both nre found to be about 20 s-~, while that of the bottom component (where the spin lict in the molecular plane) IS about 2 s-l.
