1 Introduction. The equipartition theorem 1 for canonical ensembles is one of the fundamental principles used in the statistical mechanics theory for molecular systems. This theorem can be used to show that the principle of equipartition of energy holds for Cartesian molecular models. 1,2 For the kinetic energy, this principle states that each momentum coordinate in the canonical phase space The equipartition theorem revisited. We generalize the equipartition theorem to confined systems of structureless independent molecules by introducing a confining potential, which is usually not done explicitly in most textbooks. We show that if the size of the system is much larger than the range of the confining potential, the generalization |iao| yna| hsp| sxw| qbr| tua| zdk| jbm| rup| mna| aby| qzt| dgn| hop| cah| mjm| yru| fio| glp| hqb| bei| hha| vfs| lxp| aqq| hmq| vsb| sdp| cxm| ksu| amr| pkm| qbd| hrd| ouo| pff| xmh| xag| trg| zcw| vhj| gme| ccj| dhk| wuc| dxe| cjb| ehq| pid| yzd|
