Rühle, V. and Kusumaatmaja, H. and Chakrabarti, D. and Wales, D.J. (2013) 'Exploring energy landscapes : metrics, pathways, and normal mode analysis for rigid-body molecules.', Journal of chemical theory and computation., 9 (9). pp. 4026-4034.
We present new methodology for exploring the energy landscapes of molecular systems, using angle-axis variables for the rigid-body rotational coordinates. The key ingredient is a distance measure or metric tensor, which is invariant to global translation and rotation. The metric is used to formulate a generalized nudged elastic band method for calculating pathways, and a full prescription for normal-mode analysis is described. The methodology is tested by mapping the potential energy and free energy landscape of the water octamer, described by the TIP4P potential.
