	'''Ice XI''' is the proton-ordered form of [[Ice Ih]] and was identified in 1972 by Shuji Kawada and ~~others~~ (Ref. 1-3). In principle		'''Ice XI''' is the proton-ordered form of [[Ice Ih]] and was identified in 1972 by Shuji Kawada (Ref. 1). Other researchers like Takasuke Matsuo and Hiroshi Suga, and Yoshimitsu Tajima also pioneered the study of Ice XI (Ref. 2-3) and were the authors which coined the name "Ice XI" (Ref. 3). In principle ice XI forms when ice Ih is cooled to below 72K. In practice, however, the transition is difficult to produce with pure Ice Ih samples in laboratory timescales. This difficulty is due to the long dielectric relaxation time of ice near the transition temperature, on the order tens of years (Ref. 4), which effectively freezes-in some of the proton-disorder on cooling, even when cooled at slow rates (< -0.1 K/min). Therefore, dopants like KOH are typically used to aid in the transition from Ice Ih to Ice XI by drastically reducing the relaxation time, to the order of milliseconds (Ref. 5), and allowing the transition to rapidly occur. Ice XI has an orthorhombic structure with the space group Cmc2<sub>1</sub> with eight molecules per unit cell (Ref. 6). Its lattice parameters are a=4.465(3) Å, b=7.859(4) Å, and c=7.292(2) Å at 5 K (Ref. 6).
