In this letter, we analyzed some common expressions of Shannon’s entropy used in the field of quantum chemistry. The expressions analyzed were defined in the position and momentum space, for our propose we used the first thirty-six atoms of the periodic table and a large set of molecules and only two of them fulfills with the general properties of the entropy. We compared the general trends obtained and discussed the reason about why the negative values of the continuous entropy in this field are unacceptable.

关于原子和分子中的香农熵的计算I:位置和动量空间的连续情况。

在这封信中,我们分析了在量子化学领域中使用的香农熵的一些常见表达。分析的表达式定义在位置和动量空间中,对于我们的建议,我们使用元素周期表的前36个原子和大量分子,只有其中两个满足熵的一般性质。我们比较了获得的总体趋势,并讨论了为什么该字段中的连续熵的负值不可接受的原因。
