Low-l;ring triplet electronic states have been detected in furan, thiophenc, and pyrrole by the method of variable-angle, electron-impact spectroscopy. Singlet + triplet trnnsitions CCCU~ with maximum intensity at 3.99 eV and 5.22 eV in furan, 3.75 eV and 4.62 CV in thiophene, and 4.21 eV in pyrrole
