(*Ch, degrees=True, **kwargs)[source] [edit on github][source]¶ Compute chiral angle \(\theta_c\).
\[\theta_c = \tan^{-1}\left(\frac{\sqrt{3} m}{2n + m}\right)\]Parameters: - *Ch –
Either a 2-tuple of ints or 2 integers giving the chiral indices of the nanotube chiral vector \(\mathbf{C}_h = n\mathbf{a}_1 + m\mathbf{a}_2 = (n, m)\).
- degrees (bool, optional) – If
True
, return angle in degrees.
Returns: Chiral angle \(\theta_{c}\) in degrees (default) or radians (if
degrees=False
).Return type: - *Ch –
