Abstract
To investigate the interaction between the water framework and a guest molecule in a clathrate hydrate, high‐pressure Raman scattering experiments on nitrogen guest molecules have been performed. The pressure dependence of the N2 vibron(s) at room temperature (295 K) has been determined and a new phase transition has been discovered at 0.84 GPa.Keywords
