In this paper we complete the library of synthetic spectra for the range 7650-8750Å, which includes the 8500-8750Å interval currently base-lined for the spectroscopic observations by GAIA, candidate ESA Cornerstone 5 mission. As for Paper II (Munari & Castelli, 2000A&AS..141..141M), the spectra are based on Kurucz's codes and line data. The explored metallicity, gravity and temperature ranges are -2.5≤[Z/Z_☉]≤+0.5, 4.5≤logg≤2.0 and 7750≤T_eff≤50000K, respectively. The 698 new spectra are computed at the same λ/Δλ=20000 resolving power of the observed spectra given in Paper I (Munari & Castelli, 1999A&AS..137..521M) (131 standard stars mapping the MKK spectral classification system) and the 254 synthetic spectra of Paper II (characterized by T_eff≤7500K).
