Paper Abstract

Vibrational circular dichroism (VCD) and vibrational circular birefringence (VCB) spectra were recorded with a tunable external-cavity quantum-cascade laser (QCL). In comparison with standard thermal light sources, QCLs provide orders of magnitude more power and are therefore promising for vibrational optical activity (VOA) studies in strongly absorbing solvents and longer path length cells. The brightness of this novel light source is demonstrated with IR absorption, VCD and VCB measurements of (R)-(+)-limonene.
