IR spectroscopy of H$^+$(MeOH)$_m$(H$_2$O)$_n$(m = 2 - 13, n = 1 and 2) was carried out in the OH stretch region to characterize the development of the hydrogen bond network with the cluster size. For n = 1, the band intensity of the free OH stretching mode decreased with the cluster size, and the band finally disappeared at m = 7. This result is reasonably interpreted in terms of the formation of the tricyclic structure of the hydrogen-bond network in the clusters.
