Abstract
The intriguing abundance of long linear carbon chain molecules in dark clouds such as TMC1 and in circumstellar shells such as that surrounding IRC+10216 are still not understood. Recent radioastronoray studies are beginning to confirm that more saturated analogues of the carbon chain species are not abundant. Recent laboratory studies indicate that when carbon vapour nucleates to form particles, linear chains and spheroidal shell molecules also form probably as intermediates. The results appear to have consequences as far as the formation, structures and spectroscopic properties of interstellar grains are concerned, in particular those ejected from cool carbon stars.
