abstract

  • After ascertaining that the C(p) of water confined to 1.1 nm diameter pores had been used to reach the conjecture for a lambda-transition in supercooled bulk water, we argue that only three H(2)O molecules can fit across the 1.1 nm diameter pore. Two of these form a (one-molecule thick) nanoshell hydrogen bonded to the SiO(2) pore wall. Hydrogen bonding or cooperative motions of the remaining one H(2)O molecule would not produce a "lambda-type transition."
