Raman Intensities of the ν1/ν3 Dyad of 28SiH4

0022-2852; The stimulated Raman spectrum of 28SiH4 has been recorded in the ν1/ν3 region between 2182 and 2190 cm(-1). The intensities of the Raman transitions were modeled using a dyad scheme for the two interacting bands with a first-order polarizability expansion. The involved polarizability parameter; have been adjusted to fit about 800 measured intensities of transitions reaching upper states up to J = 18. The resulting standard deviation is about 10%.
