However, tunneling splitting, the clear signature of quantum delocalization of He atoms, has rarely been identified in any of the He-containing complexes. Here, UV excitation spectra of benzene-He were extensively examined with almost full rotational resolution to identify two weak vibronic bands with vibrational excitation energies of only ∼13 and ∼16 cm-1. Each of rotational transitions appears to be split into doublets in the higher-frequency band. This splitting is attributed to quantum tunneling due to the delocalization of He spread over two minimum locations below and above the benzene ring. The magnitude of the tunneling splitting as well as the vibrational frequencies of the two vdW modes are compared with the reported theoretical prediction to quantitatively assess the intermolecular potential energy surfaces so far derived.Small chiral molecules are excellent candidates to push the boundaries of enantiodiscrimination analytical techniques. Here is reported the synthesis of two new deuterated chiral probes, (R)- and (S)-[2H]-ethyl tosylate, obtained with high enantiomeric excesses. Due to their crypto-optically active properties, the discrimination of each enantiomer is challenging. Whereas their enantiopurity is determined by 2H NMR in chiral anisotropic media, their identification was performed by combining quantum chemical calculations and vibrational circular dichroism analysis.Combined quantum mechanical/molecular mechanical (QM/MM) models using semiempirical and ab initio methods have been extensively reported on over the past few decades.
