主要采用单模脉冲染料激光系统，可提供适合绝对双光子吸收率测量的良好表征的空间和时间输出，用于研究 NOγ(0,0)S11+R21(J\ = 7-1/2) 跃迁。使用校准的诱导荧光技术，获得了 2.8±1.4×10−51 cm6 的吸收率参数。还测量了 γ(0,0) 能带中其他旋转跃迁的相对强度，结果表明，除 012(J\ = 10‐1/2) 跃迁外，所有情况下都与预测值进行了很好的比较。
A predominantly single‐mode pulsed dye laser system giving a well‐characterized spatial and temporal output suitable for absolute two‐photon absorptivity measurements was used to study the NOγ(0,0)S11+R21(J\ = 7‐1/2) transition. Using a calibrated induced‐fluorescence technique, an absorptivity parameter of 2.8±1.4×10−51 cm6 was obtained. Relative strengths of other rotational transitions in the γ(0,0) band were also measured and shown to compare well with predicted values in all cases except the 012(J\ = 10‐1/2) transition.
