Interferometrically-measured wave-lengths of 109 lines of neutral Kr[sup 84] are compared with those of Kr[sup 86]. Sixty energy levels of neutral Kr[sup 84] derived from those wavelengths and 25 Kr[sup 86]-Kr[sup 84] isotope shifts previously measured are given along with their shifts from the energy levels of Kr[sup 86]. Twenty levels of each of Kr[sup 82], Kr[sup 80], and Kr[sup 78] are also evaluated using isotope-shift information in the literature. The differences between the experimentally observed shifts and the normal mass shift leave large negative residuals which are accounted for by ionization energy differences and by the specific mass shift. It appears that the volume effect causes only a very small, if any, energy level shift.
