Notes:
High-resolution Raman spectra of isotopically pure 35Cl2 were recorded using UV argon ion laser radiation of 275.4, 300.3, 302.4 and 305.5 nm. Overtone progressions could be observed for excitation with 300.3, 302.4 and 305.5 nm radiation. All overtone transitions could be simulated satisfactorily using both the traditional Kramers-Heisenberg-Dirac equation and time-dependent quantum theory. The results obtained for 35Cl2 are compared to those derived earlier for I2 and Br2. The spectral features of the fundamental band for excitation in the UV region can be explained by assuming a destructive interference effect between resonant and non-resonant Raman scattering resulting from adjacent high-energy electronic states.
