By relating nonadiabatic effects, evaluated from analysis of only frequencies of pure rotational and vibration-rotational transitions of diatomic molecular species in several isotopic variants, to electric and magnetic properties, I determined the electric dipolar moment and rotational g factor, including the sense of electric polarity. The dipolar moment determines the intensity of the pure rotational transitions; hence we deduce information about intensities from only spectral data of frequencies of transitions of a sample without externally applied electric or magnetic field. Instances of the successful application of this approach will be presented. The method of derivation of the intensity of the vibration-rotational fundamental band, and of other bands in the same sequence, will be discussed, with applications.
