Current situation in studies of lifetimes of excited rovibronic levels for the H_2, D_2, T_2, HD, HT, and DT molecules is analyzed. All measured values of the lifetimes (792 data for 618 different vibro-rotational levels of 33 electronic states), reported in 61 publications before November 2014, are compiled and listed in the tabular format together with annotated bibliography. Experimental data are now available for the H_2, HD and D_2 molecules only. The data collected in the present work show fragmentariness of experimental data. For vast majority of the levels the lifetime value was reported in one paper only, and has no independent experimental verification. Complete bibliography of publications concerning semi-empirical determination and non-empirical calculations of the lifetimes is presented. Numerical results obtained by these two approaches are listed in an explicit form only in the cases when experimental data are available. For more than half of the levels the differences between measured and calc
