Notes. N – Number of components merged. The following columns give the J values of the lower and upper levels of the original transitions, and the J values quoted in the line list. The latter were obtained by summing up the J values occurring inthe respective level for the merged transitions (ignoring repetitions), and adding 1 in the case of integer J values and 0.5 in the case of half-integer J values.
