With the previous definitions of chi_1 and chi_2 in this sentence the K-K relationships through the rest of the article need additional factors of i to be correct. Undid my prior changes adding those factors of i, and instead corrected the definition making the old chi_2 now chi_0, new chi_2. undo Tags: Reverted Visual edit

Imaginary numbers z are often defined by z = x + iy where x and y are real and the imaginary (Im) part of z is JUST y, but in the case of the Kramers-Kronig relations the imaginary part in the commonly seen formula is actually iy. Quick check is that a factor of i will be picked up through the K-K integral, so if it were just chi2 (real, no i), the real part chi1 would be equal to something imaginary against the definition. undo Tags: Reverted Visual edit
