在OH自由基的A 2Σ+−X 2πi电子系统中测量了实验相对振动带发射系数。序列 v'=2、v"=0–5 和 v'=3、v"=0–6 的分支比是在低压甲烷-氧气火焰中使用激光诱导荧光测定的。我们考虑了旋转和振动能量转移以及荧光偏振造成的潜在误差。这些跃迁概率完成了一组实验数据，可用于单独的研究以确定 OH A-X 系统的最佳电子跃迁矩。在 OH 自由基的 A 2Σ+−X 2πi 电子系统中测量了实验相对振动带发射系数。序列 v'=2、v"=0–5 和 v'=3、v"=0–6 的分支比是在低压甲烷-氧气火焰中使用激光诱导荧光测定的。我们考虑了旋转和振动能量转移以及荧光偏振造成的潜在误差。这些跃迁概率完成了一组实验数据，这些数据用于单独的研究，以确定 OH A-X 系统的最佳电子跃迁时刻。
Experimental relative vibrational band emission coefficients have been measured in the A 2Σ+−X 2Πi electronic system of the OH radical. Branching ratios for the sequences v′=2, v″=0–5 and v′=3, v″=0–6 were determined using laser-induced fluorescence in a low pressure methane–oxygen flame. We accounted for potential error contributed by rotational and vibrational energy transfer and fluorescence polarization. These transition probabilities complete a set of experimental data, which are used in a separate study to determine the optimum electronic transition moment of the OH A-X system.Experimental relative vibrational band emission coefficients have been measured in the A 2Σ+−X 2Πi electronic system of the OH radical.
