Infrared vibrational thermal spectroscopy to study spectral energy coupling across solids in contact with liquids and gases

Abstract

Infrared vibrational thermal spectroscopy to study spectral energy coupling across solids in contact with liquids and gases. The objective of this proposed work is to build a new thermal measurement technique that monitors the energy transfer of specific vibrational modes of liquids and gases that are adjacent to a heated solid interface; the principle of this proposed technique is to use the change in absorption of the vibrational liquid or gas mode as the “thermometer” of energy transport after sub-picosecond laser heating of an adjacent metal. Our overarching hypothesis that is driving this proposed work is that different vibrational modes in a liquid or gas will have different efficiencies of energy exchange with a solid surface.
