Abstract Relative intensities of the S( J ) and O( J ) branch lines in the fundamental and overtone bands of the vibration‐rotation Raman spectrum of a linear molecule are shown to be capable of yielding the magnitude and sign of the first and second derivatives of the polarizability anisotropy, (α ∥ −α ⊥ )′ e and (α ∥ −α ⊥ )″ e in relation to the equilibrium anisotropy (α ∥ −α ⊥ ) e . The theory is applied to hydrogen and nitrogen.
