The pitch of two cholestcric mixtures of cholestcryio!cylcarbonate/cholestcrylchloridc is sensitively influenced by ambient static external pressure. The measurement of the wavelength of m&mum light reflection of these mescphases up to 2000 bars yields a remarkable red-shift. This shift can be under
