Geometrically restricted ultrathin (20-nm) film of cyclohexane: A metastable phase

We present experimental evidence that when the dimensions of cyclohexane films are finite a new metastable phase is manifested. This was ascertained from comparative infrared measurements at 90T300 K on three different-sized films of cyclohexane, i.e., 20 nm, 126 nm, and 12 {μ}m, geometrically restricted in ZnSe cylinders.
