摘要: A method to observe phosphorescence spectra for the three triplet sublevels is proposed, and applied quinoxaline in a single crystal of naphthalene‐d8. The consists measurements time resolved at temperatures where spin polarization achieved under influence microwave field saturate magnetic transition between sublevels. best cases total decay rate constants are small two Tz spectrum identical known thermally averaged observed 4 K, whereas Tx Ty markedly different from spectral distributions. relative radiative as well obtained by induced delayed some selected vibronic bands. On basis kinetic data, mechanisms which bands gain intensity discussed. Finally, t...
