    • It should be noted, that the different resolution of different QMS mass spectra was caused by exchanging some electronic parts in our QMS system during the long time span of our experiments more than 2 years, However, this did not influence the general results, since the transmission calibration was always performed with Ar-clusters to keep the transmission in the cluster mass region constant

    • In Ref, 18] we observe multiphoton photodissociation of imidazole clusters and conclude that the absorption cross section would have to be larger than 4×10-20 cm2 in order to observe this process. In addition, from the relative cross section measured in Ref, 12] it follows that the cross section at 193 nm is more than 10× larger than at 243 nm. Therefore it is probably larger than the assumed 10-19 cm2
