 In the recent development (2008), the adaptive frozen orbital (AFO) treatment of the detached bonds was suggested for FMO, making it possible to study solids, surfaces and nano systems, such as silicon nanowrires.FMO-TDDFT was also applied to the excited states of molecular crystals (quinacridone).Among inorganic systems, silica-related materials (zeolites, mesoporous nanoparticles and silica surfaces) were studied with FMO,
as well as ionic liquids and boron nitride ribbons.
