    "abstract": "Chiral structures have been found as the lowest-energy isomers of bare\n(Au$_{28}$ and Au$_{55}) and thiol-passivated (Au$_{28}(SCH$_{3})$_{16}$ and\nAu$_{38}(SCH_{3})_{24}) gold nanoclusters. The degree of chirality existing in\nthe chiral clusters was calculated using the Hausdorff chirality measure. We\nfound that the index of chirality is higher in the passivated clusters and\ndecreases with the cluster size. These results are consistent with the observed\nchiroptical activity recently reported for glutahione-passivated gold\nnanoclusters, and provide theoretical support for the existence of chirality in\nthese novel compounds.",
