| Abstract: | The 1Δg state of liquid oxygen (natural O2 and 18O2) was excited by intense Nd: YAG laser pulses. The observed fluorescence decay is non-exponential and depends on pump laser intensity. Various decay channels of the 1Δg state are discussed. The energy pooling reaction 1Δg + 1Δg → 1Σ+g + 3Σ?g is verified experimentally. Values f constant of liquid natural O2 and 18O2 are given. |
