I'm trying to calculate the structure factor for a polymer melt: S(q)=[tex]\sum_{k}[/tex][tex]\sum_{j}[/tex][tex]\epsilon^{i*<q>*<r_{kj}>}[/tex], but I don't know how to deal with the imaginary exponent...(the rest of the variable don't really matter, because I'm confused about how to deal with the exponent, but q is the scattering vector, and r[tex]_{kj}[/tex] is the distance between vectors k and j) my first thought was to multiply by the complex conjugate, but doesn't that just get rid of the exponential altogether, leaving nothing for you to add? I don't understand how I can get any data if I multiply by the complex conjugate. Anyone have any suggestions?
