dc.description.abstract	A time‐of‐flight method for measurement of the lifetime of metastable molecules is described. The method is applicable to a molecules in several different metastable excited states. As compared to methods used previously, the method has the advantages that it does not require selective excitation or quenching of the different states; moreover, it does not require a determination of the relative populations or velocity distributions of molecules in the excited states. The feasibility of the method is demonstrated with a measurement of the lifetime of the a 1πg state of N2.	en_US
