title: Some properties of Ti-related paramagnetic centres relevant for electron spin resonance dating of single sedimentary quartz grains.
abstract: We performed Q-band ESR spectroscopy on several single quartz grains from different geological deposits. Various properties of Ti-related impurity centres in quartz relevant for ESR dating were studied. It will be shown that some properties, such as sensitivity change and response to artificial gamma-irradiation, may vary from grain to grain. It is concluded that single grain ESR dating is feasible at a pure experimental level.
