Abstract
The sol to gel transition in a bulk gel is a macroscopic event which can be followed using different analytical methods, and even if an accurate determination of the gelation time is always a difficult task, it is possible to obtain reliable measures especially by a combination of several techniques. The liquid phase of the gel remains, even after gelation, a peculiar chemical environment with a specific microviscosity. This evolves with drying, while diffusion inside the pores is always possible. The methods used to probe this microenvironment and sol-gel transition in thin films are the subject of this chapter.
