在无碰撞条件下，利用状态选择激发和测量随后荧光的时间衰减，测量了CO分子的a' 3 π +（v=14）和e 3 π-（v=5）态的各个旋振能级的辐射寿命.测量的准确度通常为3%至5%。未扰动的三重态寿命和相应的自旋轨道相互作用常数已被确定。根据Field和同事的数据，发现测量的寿命和计算的寿命之间非常一致。它还表明，在有利的条件下，寿命测量是显着更敏感的混合系数<$β <$2比波长测量。
Radiative lifetimes of individual rovibronic levels of the perturbed a’ 3Σ+(v=14) and the e 3Σ−(v=5) states of the CO molecule have been measured under collision‐free conditions using state selective excitation and measuring the temporal decay of the subsequent fluorescence. The accuracy of the measurements was typically 3% to 5%. The unperturbed triplet lifetimes and the corresponding spin‐orbit interaction constants have been determined. Excellent agreement was found between the measured and the calculated lifetimes based on data of Field and co‐workers. It is also shown that under favorable conditions lifetime measurements are significantly more sensitive to the mixing coefficients ‖β‖2 than wavelength measurements.
