Abstract |
Molecular interactions between achiral and chiral molecules can give rise to circular dichroism within the absorption region of the achiral molecule. This is called induced circular dichroism (ICD). Most ICD spectroscopy has been extensively used to probe the molecular interactions in solution, which only exhibit the averaged CD values of all conformational isomers in solution. Here, we obtained the first ICD spectra by using resonant two-photon ionization CD spectroscopy to jet-cooled phenol complexes with methyl lactate (PhOH-ML). The R2PI spectra of PhOH-ML exhibit well-resolved vibronic bands of two different conformers, which have different ICD signs and magnitudes. The ICD effect will be discussed in the geometrical asymmetries of the complexes and the electronic coupling strengths between PhOH and ML. |
