thermodynamics - Can a single molecule have a state?


I was studying a book about thermodynamics of nanosystems and I got stuck with this question in my mind which I couldn't find an answer for.


For instance, does a single water molecule have a state, like being liquid or something? Or is one molecule of TiO2 solid or gas? I would appreciate if anyone could clarify this.


I should state that I am not considering a macromolecule in my case.
