Approximate magnetic susceptibility of these liquid propellants?
As it has been pointed out, molecular oxygen is paramagnetic. It is exceptional in that. Usually, you require either a transition metal ion, or a lanthanide ion, or a radical, for a molecule to be paramagnetic.
For most other molecules, including as far as I can tell the fuels you mention, you can safely assume that they are diamagnetic. Paramagnetism is relatively tricky and intense, diamagnetism, at least in its magnitude, is weak and comparatively straightforward to estimate.
If one wants an inexpensive, ballpark estimate of diamagnetism, many people use Pascal's constants, additive terms considering the involved atoms, with corrections for certain bonds. Rather than Pascal's original work, maybe check out the widely cited Gordon A. Bain and John F. Berry, Diamagnetic Corrections and Pascal's Constants, J. Chem. Educ. 2008, 85, 4, 532.
