Abstract
Coherent anti-Stokes Raman Scattering (CARS) spectroscopy proved to be a powerful tool for diagnostics of states and phase transitions of molecular media confined in nanopores [1-3]. Contributions of gas phase, molecular layers adsorbed on the pores surface and liquid-like condensed state inside pores can be recognized using the analysis of measured CARS spectra. Phase transitions can be revealed by appearing or disappearing of corresponding contributions in measured spectra. In present investigation we apply CARS to study condensation of carbon dioxide in different nanoporous glass samples (NGS) with pores of several nanometers.
