Constituent H2O crystalline - phase Ih and/or Ic

Constituent

Family: molecular solid
Class: hydrogen bonded molecular solid
Compound type: inorganic molecular solid
Comments: Subsequent to the process of deposition, the crystalline ice film was cooled to the desired irradiation temperature (20-120 K). It is important to note that, in this context, "crystalline water ice" is referring to either the metastable cubic Ic or the hexagonal Ih crystalline forms of water ice. However, the precise crystalline nature of thin films remains uncertain due to the presence of stacking disorders during the film’s growth process.
