Abstract

Abstract: Singlet oxygen arising from the thermal decomposition of the water-soluble endoperoxide of 3, 3'-(1, 4-naphthy1idene) dipropionate (NDP02) or from hypochlorite/H202 was detected. Direct measurements of light emission due to the chemiluminescent transition of O2 ('A,) to the triplet ground state was monitored (a) by monomol emission in the near- infrared (1270 nm) with a liquid nitrogen cooled germanium diode and (b) by dimol ...
