[交流] 求问如何计算某个原子偏离相连平面的距离

如何计算某个原子偏离相连平面的距离呢?如一个苯环上连有一个大环但有些原子不在苯环平面上,计算这些原子离平面的距离。请详细些呀。最好是XP,或者PLATON,merury等常用软件

PLATON中的 L.S.-PLANE 也可以计算

具体见:

http://www.cryst.chem.uu.nl/platon/pl090224.html


Interactive calculation of least squares planes.
The Plane definition starts with clicking on the Lspl button followed by clicking on the atom centres of the atoms participating. The sequence is ended (and the calculation initiated) by clicking in the End field.

Plane determining atoms may be separated from those for which the distance to the plane only has to be calculated by clicking on the Dist field between the clicks on atoms.

Alternatively, an instruction similar to LSPL c3 c4 c5 DIST c1 could be issued from the keyboard.

Atoms are treated with unit-weight by default. Alternatives are weighting based on atomic weights and standard deviations (esd, su). The weighting scheme may be changed using the (UAE)WLSPL button.

可以在.ins中添加instruction
比如
MPLA 6 C1 C2 C3 C4 C5 C6 C7
6表示有六个面上原子, 为C1, C2 到C6, C7就是面外原子.
