请问:
The basal spacing (Ic) calculated by Bragg equation and
Ic=[di+3.35*(n-1)]/L(di is the interlayer distance, n is the
stage number) is 1.325 nm. In the case n = 3, the interlayer distance
calculated is 0.655 nm.
The basal plane is the plane perpendicular to the principal axis in these crystal systems. For triclinic, orthorhombic, and cubic crystal systems the axis designation is arbitrary and there is no principle axis.
interlayer distance between two graphite layers
从你给的数据看来 13.25=6.55+3.35*(3-1) 公式应该如下面的图所显示
其中,图3和图4中的di和ds是一个意思 可以看图2我做的标示
