Abstract

The condensation parameter (c.p.) and the condensation coefficient (c.c., sticking probability) of vapours consisting of polyatomic molecules are determined by using a shock-tube. The c.p. and the c.c. for three kinds of vapour are deduced from the comparison between experiment and gasdynamical theory with molecular gasdynamical boundary conditions. It is found that the experimental values of c.p. and c.c. of these vapours are significantly less than those for the complete capture of molecules on their condensed surfaces. The transition state theory suggests that these small values are due to that the rotational degrees of freedom of molecules in the liquid state are hindered in comparison with those of molecules in the gas state.
