Is the metastable phase kinetically hindered
Transitions from metastable excited levels are typically those forbidden by electric dipole selection rules. This means that any transitions from this level are relatively unlikely to occur. In a sense, an electron that happens to find itself in a metastable configuration is trapped there.

WitrynaThe nucleation of metastable germanium polymorphs on decompression is studied using insitusynchrotron x-ray diffraction. We show that the transition pathway is critically dependent on the hydrostaticity. Quasihydrostatic conditions result in the nucleation of the rhombohedral r8 phase, followed by the cubic bc8 and hexagonal diamond phases. bluetooth aux balmuda the speaker m01a-bkWitryna1 gru 2006 · The equilibrium phase behavior of aqueous carbohydrate systems may be a simple eutectic system.
