ABSTRACT:
The method comprises measuring the heat transfer between a specimen of the substance in condensed phase and an ambient gas. The heat transfer is detected by measurement of the amplitude of the angular movement of a pencil of light which is directed substantially parallel to the surface of the specimen subjected to energization variable in time, and which passes through an area located close to said surface. The device comprises a specimen support and a monochromator.
