In this paper we complete the library of synthetic spectra for the range 7650-8750 Å, which includes the 8500-8750 Å interval currently base-lined for the spectroscopic observations by GAIA, candidate ESA Cornerstone 5 mission. As for Paper II, the spectra are based on Kurucz's codes and line data. The explored metallicity, gravity and temperature ranges are -2.5<= [Z/Zsun]<= +0.5, 4.5<=log g<= 2.0 and 7750<=Teff <=50 000 K, respectively. The 698 new spectra are computed at the same lambda / bigtriangleup lambda =20 000 resolving power of the observed spectra given in Paper I (131 standard stars mapping the MKK spectral classification system) and the 254 synthetic spectra of Paper II (characterized by Teff <= 7 500 K). Tables 2-4 are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/366/1003 or via the personal HomePage http://ulisse.pd.astro.it/Astro/Atlases/ The spectra are available in electronic form at the CDS. Figures 5-224 are only available in electronic form at http://www.edpsciences.org
