 Dear colleagues:
 I'm using MOPAC6 to calculate the atomic electron density in indole.
 I found that the atomic electron densities calculated by MOPAC are quite
 different from those
 reported in the literature (Theoret. Chim. Acta, 1970, 16, 22-32). For instance,
 Mopac reports
 that the electron density for the N atom in indole is 5.2213 (using AM1) while
 the one reported
 in the literature is 1.69.
 Could anybody please tell me why  the huge difference?
 I'll post a summary.
 Thanks a lot in advance.
 Guillermo.
