In this study, we measured the two-photon spectra of the 5s[3/2]2→5d[7/2]4 transition of Kr atoms. The dependence of the spectra on gas pressure and discharge current was also confirmed. Nuclear magnetic and nuclear quadrupole interaction constants were calculated from the 83Kr hyperfine structure line splitting and compared with the results of Cannon et al. In order to determine the spectral positions of 83Kr in the unperturbed line position, the 83Kr frequency shift and 82,84,86Kr isotope shifts were used to analyze the Bohr shift, specific mass shift, and volume shift by King's method.
