The hyperfine structure (hfs) of the spectrum of Nb I was studied by means of a liquid-air-cooled hollow cathode discharge tube and a Fabry-Perot etalon. The quadrupole moment of Nb^<93> was deduced to be -0.29 barn and -0.20 barn (1 barn = 10^<-24>cm^2) from the levels 4d^35_8^2 ^4<F>_<3/2> and 4d^45_8 ^6<D>_<3/2> respectively, in which no shielding correction is included. Assuming that the shielding correction in this case is zero, we get Q(Nb^<93>) = -0.2_5±0.1_5 barn. The interval factors of the levels 4d^35_8^2 ^4<F>_<3/2, 6/2, 7/2, 9/2> and 4d^45_8 ^0<D>_<3/2, 5/2, 7/2, 9/2> were measured and compared with hfs formulas, and a small but definite discrepancy was detected.
