Resonant two photon ionization spectra of the benzene:diacetylene 1:1 cluster have been taken across the 610 transition region of the cluster with time-of-flight mass spectrometry detection. IR/UV holeburning has shown that one of the peaks in the spectrum is the benzene:diacetylene 1:2 cluster. The resonant ion dip infrared spectra of both the 1:1 cluster and the 1:2 cluster have been recorded. Possible structures of these clusters will be discussed.
