The vibrational Raman optical activity of deuterated 1-methylindanes

W. Hug; A. Kamatari; K. Srinivasan; Hans-Jürgen Hansen; H.-R. Sliwka

Abstract High quality VROA spectra disprove the idea of a methyl torsional mode leading to sizable optical activity above 220 cm −1 in arylethanes. The analysis of the 1450 cm −1 region shows that VROA. provides unique information on the coupling of vibrations in large molecules.
