    • ‘These align constructively along the helical axis to form macrodipoles (positive axis N-terminal) of 39, 43, and 59 debyes.’
    • ‘All the structures have a rather large moment of 800'Äì1 800 debyes, aligned roughly along the gorge axis, and both centering methods agree to within 20%.’
    • ‘Similarly, the dipole moment of methanol, another extremely polar substance, is only 2.9 debyes.’
