Theoretical spectral energy distributions are computed for a grid
of hydrogen-deficient and carbon-rich model atmospheres with a
range in Teff of 
K and 
of 
,
using the technique of opacity sampling, and taking into account
continuous, atomic line and molecular band absorption. The
energy distributions are compared with the spectrum of V4334 Sgr
(Sakurai's object) of August 12, 1998 in the wavelength interval
nm. This comparison yields an effective temperature of
V4334 Sgr of 
, and a value for the
interstellar plus circumstellar reddening of 
.
