Vibrational Raman optical activity (ROA) measurements are reported on single-stranded poly(rA) and double-stranded poly(rA)โขpoly(rU) in the temperature range 2 -45 โข C. The intensities of one ROA couplet in poly(rA) (centred at ca 1329 cm -1 and sensitive to sugar-base conformation) and three in pol

## Abstract A new tool for chiral vibrational spectroscopy is reported here. A surface enhanced effect was observed using Raman optical activity (ROA). This observation opens new possibilities for ROA as a tool for vibrational spectroscopy. The combination of surface enhanced effect (SE) and ROA in
The backscattered Raman and Raman optical activity (ROA) spectra of poly(rA) -poly(rU) at 20ะC and 45ะC in buffered aqueous solution between 650 and 1750 cm 01 are reported. Although the intensity of the majority of the Raman bands increase by varying amounts as the temperature is raised in accordan
