In agreement with Molski's derivation of an insignificant value t0Kr = -0.0146 \pm 0.0335 of a parameter related to the rotational g factor, our objective fit of 352 appraised measurements of frequencies of pure rotational transitions and wave numbers of vibration-rotational transitions of KrH+ in various isotopic species 78,80,82,83,84,86Kr1,2H+ indicates that one might estimate a value of the rotational g factor if adiabatic corrections be negligible, but that no corresponding estimate of the permanent electric dipolar moment is practicable. The application of computational spectrometry to the prediction of an accurate wave number of the pure fundamental vibrational transition of LiH is also discussed.
