The charge-transfer rate coefficients of Fe{sup 3+} with H{sub 2} and N{sub 2} are measured by using a laser-ablation ion source and a quadrupole radio-frequency ion trap with the mean collision energy of about 5.1 eV. The rate coefficients for Fe{sup 3+} with H{sub 2} at the equivalent temperature 1.7x10{sup 3} K and Fe{sup 3+} with N{sub 2} at 1.3x10{sup 4} K are 1.64(0.22)x10{sup -10} cm{sup 3} s{sup -1} and 4.36(0.46)x10{sup -9} cm{sup 3} s{sup -1}, respectively. The measured values are of the same order as the Langevin rate coefficient.
