1,1-BI-2-NAPHTHOL SOLUTIONS UNDER UV-NEAR-RESONANCE RAMAN SCANNING

Abstract

Measurements of the normal and UV near-resonance Raman spectra of BN in basic solution were made and analysed, and the results were published. Ground state geometry, vibrational frequencies, off-resonance Raman intensities and depolarization ratios of 1,1-bi-2-naphtholate dianion were studied using density functional theory (DFT) computations (BN2-). The observed Raman bands were allocated in detail based on the estimated and experimental findings of î, I, and F. UV resonance Raman spectra showed a substantial increase in the 1612 cm-1 Raman band of BN compared to the conventional Raman spectrum. According to depolarization ratios for the 1366 and 1612 cm-1 bands, it is clear that both transitions polarizabilities contribute to the 1366 cm-1 band, whereas onlytransitions polarizabilities contribute to 1612.
