  A novel heterodyne polarimetry system determines the frequency dependence
from 900 to 1100 cm^-1 and temperature dependence from 35 to 330 K of the Hall
transport in single crystal, optimally doped BSCCO. The results show a
significant disconnect from the behavior of the Hall angle in the existing data
for YBCO in the far-infrared, which indicate a negative value for the real part
of the Hall angle above 250 cm^-1, whereas that of the current work at 1000
cm^-1 is positive. The current work when analyzed using an extended Drude
formalism results in a Hall mass comparable to the ARPES Fermi mass and a
scattering rate comparable to the low frequency conductivity and Hall effect
scattering rates, which, however, are only 1/4 of the ARPES values.
