# chemcoord.Cartesian.get_dihedral_degrees¶

Cartesian.get_dihedral_degrees(indices, start_row=0)

Return the dihedrals between given atoms.

Calculates the dihedral angle in degrees between the atoms with indices i, b, a, d. The indices can be given in three ways:

• As simple list [i, b, a, d]
• As list of lists: [[i1, b1, a1, d1], [i2, b2, a2, d2]...]
• As pandas.DataFrame where i is taken from the index and b, a and dfrom the respective columns 'b', 'a' and 'd'.
Parameters: indices (list) – Vector of angles in degrees. numpy.ndarray
