Abstract
The analysis of the sample of southern globules investigated by Scappini et al. in the CO (4-3) transition has been extended using a statistical equil ibrium-radiative transfer model and making use of the results of Bourke et al. and Henning & Launardt for those globules. CO column densities and exci tation temperatures have been calculated and the results compared with a ch emical model representative of the chemistry of a spherical dark cloud. In a number of cases the gas kinetic temperatures have been constrained.
