measurements of the vapor-phase cotton-mouton effects of methane, methyl chloride, chloroform, and carbon tetrachloride over a range of temperature and pressure are reported. analysis of the results shows that the magnetic hyperpolarizability anisotropy (10/sup 50/ delta eta /c m/sup 2/v/sup -1/t/sup -2/) is positive in sign for all four molecules and tends, overall, to increase in magnitude as the number of chlorine substituents increases (ch/sub 4/, 11.3+or-1.5: ch/sub 3/cl, 47+or-33: chcl/sub 3/, 150+or-70: ccl/sub 4/, 75+or-23). reliable values of the magnetic anisotropies (10/sup 29/ delta chi /j t/sup -2/) of methyl chloride and chloroform are obtained (ch/sub 3/cl, -15.0+or-1.3: chcl/sub 3/, 22.7+or-1.9), and these, in combination with the known mean magnetizabilities, yield the individual components of the molecular magnetizability tensors
