Fig. 1

a Experimental spectrum from ref. 13. b Experimental spectrum from ref. 9. c Calculated spectrum (red-shifted 70 cm−1 to match experimental line positions). Both experimental spectra detected via photodissociation of D2 tagged clusters. The assignments of the peaks follow the nomenclature of refs. 9, 13 and are discussed in Supplementary Table 1.
