Vibrational-rotational structure in the resonance Raman effect of iodine vapor

The overtone progression in the resonance Raman effect of iodine vapor shows a remarkably fine structure. The observed resonance Raman lines can be explained in terms of Q branches, S bandheads and vibrational “hot” band structure. Comparing the observed Raman spectra with calculated Q, S and O bran...

Description
Summary:The overtone progression in the resonance Raman effect of iodine vapor shows a remarkably fine structure. The observed resonance Raman lines can be explained in terms of Q branches, S bandheads and vibrational “hot” band structure. Comparing the observed Raman spectra with calculated Q, S and O branches, using spectroscopic constants derived from the high resolution fluorescence measurements of Rank and Rao, we have been able to assign all observed Raman lines. The spectroscopic constants ω e and ω e x e for the ground state of iodine have been determined, whereas the constants ω e y e and α e could only be estimated.
