The thermo physical parameters thermal effusivity (e) and thermal
diffusivity (α) have been measured using Fourier transform infrared (FTIR)
Photoacoustic spectroscopy (PAS) for two different purities of C60 fullerenes
(99.5 % , 98.5%) samples in the powder form. The experimental results shows
that the values of thermal diffusivity is less then that obtained for crystalline C60
fullerenes. The data obtained are comparable with those obtained by
microscopic infra-red radiometry
