The dependence of the population dynamics on intensity, time, wavelength and polarisation of the illuminating light and on the temperature of both metastable states in Na 2 [Fe(CN)sNO]. 2H20 single crystals is investigated by differential scanning calorimetry. The population and depopulation behaviour can be described by exponential functions. The wavelength dependence shows the spectral range in which both states can be excited and the existence of a transfer process from state II into state I. Further, light of the near infrared region, transfers state I into state II.
Elastic and thermoelastic properties of the 21 title crystalline species have been determined from ultrasonic resonant frequencies of plates and their shift upon variation of temperature, respectively. In addition, the tensors of thermal expansion have been measured by the aid of a Fizeau interferometer. An analysis of the elastic behaviour of organic crystals, including earlier elastic data of other organic compounds taken from the literature, revealed common features of organic crystals and organic liquids in respect to the scalar invariants
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
