Hydrogen-bond network is ubiquitous and plays important roles in various phenomena involving chemical reactions, biological processes, and so on. To understand microscopic natures of hydrogen-bond network, gas-phase molecular clusters have been treated as a simple model in a huge number of studies. Although temperature is one of general parameters in discussing a hydrogen-bond network, to control the temperatures of molecular clusters is rather difficult. In the preset article, we introduce mainly two methods for the control of the temperatures of the cluster ions, a tagging technique and a use of cold ion trap. Then, we explain our recent results on the temperature effect on the microscopic hydration structures of phenol cation. In this work, we succeeded in discussing a quantitative change in the relative abundance between the isomers having distinct hydration structures based on our experimental observation.
