摘要：

We measured the viscosities and infrared (IR) spectra before and after hydrate nucleation. During the induction period, the viscosity increases and the infrared spectrum shifts to higher energy. After nucleation, the viscosity decreases abruptly, and the peak positions in the IR spectrum change to the small wave-number side. These results indicate that water acts as a precursor to hydrate nucleation.
