测定了12种脂肪烃在气相中猝灭O_2（1 μ g ~+）的速率常数。速率常数的大小取决于猝灭剂在O2（1 μ g+）弛豫为O2（1Δg）时振动激发的能力，通过将速率常数与猝灭剂在O2（1 μ g+−1Δg）跃迁频率处的吸收光谱联系起来，对所得方程进行了定量检验。
Rate constants for the quenching of O2(1Σg+) in the gas phase have been determined for 12 aliphatic hydrocarbons. The values are discussed in terms of a mechanism in which the magnitudes of the rate constants are determined by the abilities of the quenchers to become vibrationally excited when O2(1Σg+)is relaxed to O2(1Δg).The resulting equations are tested quantitatively by relating the rate constants to the absorption spectra of the quenchers at the frequencies of the O2(1Σg+−1Δg) transition.
