作者用非弹性电子-光子符合技术测量了一氧化碳B1Sigma+态的前两个振动能级的寿命。它们的值分别为21.8+或-0.3和15.5+或-0.7 ns。他们将这种对振动量子数的依赖归因于B-X跃迁矩对核间距的强烈依赖，并在r质心近似下确定了这种跃迁矩。
The authors have measured the lifetimes of the first two vibronic levels of the B1 Sigma + state of carbon monoxide using the inelastic electron-photon coincidence technique. Their respective values are 21.8+or-0.3 and 15.5+or-0.7 ns. They attribute this dependence on the vibrational quantum number to a very strong dependence of the B-X transition moment on the internuclear distance and have determined this transition moment in the r centroid approximation.
