2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/107940We propose a detail theoretical approach modeling molecular librations in liquid investigated by ultrafast optically heterodyne detected optical Kerr effect (OHD-OKE). The approach has been applied for fluoroform molecular liquid and new information about spectrum, relaxation time and time domain librations has been obtained.12 pages, 2 figuresChemical Physicstext
