Abstract
Structural information in the local electric field produced by helical charge distributions, such as dissolved DNA, is revealed in a straigh tforward manner employing cylindrical coordinates. Comparison of struc ture factors derived in terms of cylindrical and helical coordinates i s made. A simple coordinate transformation serves to relate the Green function in cylindrical and helical coordinates. We also compare the e lectric field on the central axis of a single helix as calculated in b oth systems.
