ABSTRACT
The molecular cluster ions HSO[sub 4][sup -](H[sub 2]SO[sub 4])[sub n-1] corresponding to the neutral species (H[sub 2]SO[sub 4])[sub n] for n = 3 to 8 have been observed using a transverse chemical ionization scheme located inside a cooled flow tube. The contribution of ion-molecule clustering reactions was ascertained and readily separated from the ionization of the neutral clusters. The presence of the clusters were strongly dependent on temperature and humidity. Ratios of successive clusters thought to be representative of steady-state are reported.

    We clarify some of the subtle issues surrounding the observational cluster method, a simulation technique for studying nucleation. The validity of the method is reaffirmed here. The condition of the compact cluster limit is quantified and its implications are elucidated in terms of the correct...

    We use nucleation theorems to extract the excess internal energy of small molecular clusters of n-pentanol from experimental droplet nucleation rates. Corrections to the theorems are derived, in order to take into account the nonideality of the vapor phase, but these have only a small effect on...

    We have performed a series of computer simulations using the AVUS-HR approach to better understand the origin of the sign preference in ion-induced nucleation. In particular, we emphasize the importance of distinguishing between the total formation free energy of a cluster, and the nucleation...
