The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. External parameters generally means the volume, but may include other parameters which are specified externally, such as a constant magnetic field. sks southern sdn. bhdWeb14 apr. 2006 · Here, the minimal energy path NEB model for the GG conformational change is described.
