The Raman spectra of the vibrational fundamental, first overtone and second overtone transitions of the H{sub 2} molecule were recorded using visible and ultraviolet argon--ion laser excitation. The ratios of transition polarizability matrix elements, {alpha}{sub 01,21}/{alpha}{sub 01,11} and {alpha}{sub 01,31}/{alpha}{sub 01,11}, were determined from the measured intensities of the {ital Q}(1) Raman lines {ital v},{ital J}=0,1{r arrow}{ital v}{prime},1 for {ital v}{prime}=1,2,3. The experimentally determined value of the Raman first overtone matrix element is in good agreement with the value from the best {ital ab} {ital initio} calculation.
