Gspann parameter

Replacing y with the modified Gspann parameter y in equation 3a leads to ... 

Using eqs. (6-1) and (6-2) with experimental values of f, t0, and D, the Gspann parameter y and heat capacity C may be determined. Since the cluster (inter-molecular) modes are much more important than the internal molecular motions in the evaporative dissociation process of a cluster containing n molecules, C is chosen to be proportional to n — 1. 

Klots (1991) has suggested that the ratio AE p/k Tf, = y is approximately constant and has named it the Gspann parameter. [Gspann (1982) first proposed that the rate of... 

With the substitution of the Gspann parameter into Eq. (10.57), the fraction of dissociated clusters in the meta-stable time range is... 

The heat of vaporization AS ap has been replaced by Afi to indicate that this quantity varies with cluster size. Interestingly, the Gspann parameter, 7 = is...
