NIR-absorption and NIR-VCD spectroscopy can teach us a lot about OH bonds Abstract – We briefly review the local mode model and its usefulness to interpret simply and effectively the near infrared absorption and near infrared vibrational circular dichroism spectra (NIR and NIR-VCD respectively). In particular we consider the case of the OHstretching first overtone region between 6250 and 7700 cm-1 (1600 and 1300 nm). With reference and by comparison of newly acquired data for chiral phenylethanol and chiral 2,2,2-trifluorophenylethanol, we show that NIR VCD spectra in that region are quite informative about the OH bond, more than the corresponding fundamental region, between 3000 and 3800 cm-1, which is more accessible to standard instrumentation.
