Vibrational circular dichroism is a powerful technique to study the stereochemistry of chiral molecules, but often suffers from small signal intensities. Electrochemical modulation of the energies of the electronically excited state manifold is now demonstrated to lead to an order of magnitude enhancement of the differential absorption. Quantum-chemical calculations show that increased mixing between
振动圆二色性是研究手性分子立体化学的强大技术,但通常信号强度小。现在证明了电子激发态歧管的能量的电化学调制导致差分吸收的数量级增强。量子化学计算表明,基态与激发态之间的混合增加是这种放大作用的起源。
